USB-serial fixes for 5.15-rc3
Here's a fix for a regression affecting some CP2102 devices and a host
of new device ids.
Included are also a couple of cleanups of duplicate device ids, which
are also tagged for stable to keep the tables in sync, and a trivial
patch to help debugging cp210x issues.
All have been in linux-next with no reported issues. Note however that
the last last two device-id commits were rebased to fix up a lore link
in a commit message (as the patch itself never made it to the list).

Update the current state as boot state during dpm initialization.
During the subsequent initialization, set_power_state gets called to
transition to the final power state. set_power_state refers to values
from the current state and without current state populated, it could
result in NULL pointer dereference.
For ex: on platforms where PCI speed change is supported through ACPI
ATCS method, the link speed of current state needs to be queried before
deciding on changing to final power state's link speed. The logic to query
ATCS-support was broken on certain platforms. The issue became visible
when broken ATCS-support logic got fixed with commit
f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

For xnack off, restore work dma unmap previous system memory page, and
dma map the updated system memory page to update GPU mapping, this is
not dma mapping leaking, remove the WARN_ONCE for dma mapping leaking.
prange->dma_addr store the VRAM page pfn after the range migrated to
VRAM, should not dma unmap VRAM page when updating GPU mapping or
remove prange. Add helper svm_is_valid_dma_mapping_addr to check VRAM
page and error cases.
Mask out SVM_RANGE_VRAM_DOMAIN flag in dma_addr before calling amdgpu vm
update to avoid BUG_ON(*addr & 0xFFFF00000000003FULL), and set it again
immediately after. This flag is used to know the type of page later to

This reverts commit 437b38c51162f8b87beb28a833c4d5dc85fa864e.
The memory semantics added in commit 437b38c51162 causes SystemMemory
Operation region, whose address range is not described in the EFI memory
map to be mapped as NormalNC memory on arm64 platforms (through
acpi_os_map_memory() in acpi_ex_system_memory_space_handler()).
This triggers the following abort on an ARM64 Ampere eMAG machine,
because presumably the physical address range area backing the Opregion
does not support NormalNC memory attributes driven on the bus.

If the Opregion address range is not present in the EFI memory map there
is no way for us to determine the memory attributes to use to map it -
defaulting to NormalNC does not work (and it is not correct on a memory
region that may have read side-effects) and therefore commit
437b38c51162 should be reverted, which means reverting back to the
original behavior whereby address ranges that are mapped using
acpi_os_map_memory() default to the safe devicenGnRnE attributes on
ARM64 if the mapped address range is not defined in the EFI memory map.

After fixing hibernation resume flow, another usecase was found which
should be explicitly handled - resume when device is in "down" state.
Invoke aq_nic_init jointly with aq_nic_start only if ndev was already
up during suspend/hibernate. We still need to perform nic_deinit() if
caller requests for it, to handle the freeze/resume scenarios.

The blamed commit made the fatally incorrect assumption that ports which
aren't in the FORWARDING STP state should not have packets forwarded
towards them, and that is all that needs to be done.
However, that logic alone permits BLOCKING ports to forward to
FORWARDING ports, which of course allows packet storms to occur when
there is an L2 loop.
The ocelot_get_bridge_fwd_mask should not only ask "what can the bridge
do for you", but "what can you do for the bridge". This way, only
FORWARDING ports forward to the other FORWARDING ports from the same
bridging domain, and we are still compatible with the idea of multiple
bridges.

SPI modalises. Supporting OF modalises is going to be difficult if not
impractical, an attempt was made but has been reverted, so ensure that
module autoloading works for this driver by adding the part name used in
the compatible to the list of SPI IDs.

syzkaller discovered memory leaks [1] that can be reduced to the
following commands:
# ip nexthop add id 1 blackhole
# devlink dev reload pci/0000:06:00.0
As part of the reload flow, mlxsw will unregister its netdevs and then
unregister from the nexthop notification chain. Before unregistering
from the notification chain, mlxsw will receive delete notifications for
nexthop objects using netdevs registered by mlxsw or their uppers. mlxsw
will not receive notifications for nexthops using netdevs that are not
dismantled as part of the reload flow. For example, the blackhole
nexthop above that internally uses the loopback netdev as its nexthop
device.
One way to fix this problem is to have listeners flush their nexthop
tables after unregistering from the notification chain. This is
error-prone as evident by this patch and also not symmetric with the
registration path where a listener receives a dump of all the existing
nexthops.
Therefore, fix this problem by replaying delete notifications for the
listener being unregistered. This is symmetric to the registration path
and also consistent with the netdev notification chain.
The above means that unregister_nexthop_notifier(), like
register_nexthop_notifier(), will have to take RTNL in order to iterate
over the existing nexthops and that any callers of the function cannot
hold RTNL. This is true for mlxsw and netdevsim, but not for the VXLAN
driver. To avoid a deadlock, change the latter to unregister its nexthop
listener without holding RTNL, making it symmetric to the registration
path.

Some CP2102 do not support event-insertion mode but return no error when
attempting to enable it.
This means that any event escape characters in the input stream will not
be escaped by the device and consequently regular data may be
interpreted as escape sequences and be removed from the stream by the
driver.
The reporter's device has batch number DCL00X etched into it and as
discovered by the SHA2017 Badge team, counterfeit devices with that
marking can be detected by sending malformed vendor requests. [1][2]
Tests confirm that the possibly counterfeit CP2102 returns a single byte
in response to a malformed two-byte part-number request, while an
original CP2102 returns two bytes. Assume that every CP2102 that behaves
this way also does not support event-insertion mode (e.g. cannot report
parity errors).

Sadly this will mean that anything that started loading since the

least bad approach - gory details are in the commit log for the

The gpio driver runs into issues on v1 gpio blocks, as the db_clk
and the whole extended debounce support is only ever defined on v2.
So checking for the IS_ERR on the db_clk is not enough, as it will

Fix this by adding the needed condition for v2 first before checking
the existence of the db_clk.

Commit 8dcb7a15a585 ("gpiolib: acpi: Take into account debounce settings")
made the gpiolib-acpi code call gpio_set_debounce_timeout() when requesting
GPIOs.
This in itself is fine, but it also made gpio_set_debounce_timeout()
errors fatal, causing the requesting of the GPIO to fail. This is causing
regressions. E.g. on a HP ElitePad 1000 G2 various _AEI specified GPIO
ACPI event sources specify a debouncy timeout of 20 ms, but the
pinctrl-baytrail.c only supports certain fixed values, the closest
ones being 12 or 24 ms and pinctrl-baytrail.c responds with -EINVAL
when specified a value which is not one of the fixed values.
This is causing the acpi_request_own_gpiod() call to fail for 3
ACPI event sources on the HP ElitePad 1000 G2, which in turn is causing
e.g. the battery charging vs discharging status to never get updated,
even though a charger has been plugged-in or unplugged.
Make gpio_set_debounce_timeout() errors non fatal, warning about the
failure instead, to fix this regression.
Note we should probably also fix various pinctrl drivers to just
pick the first bigger discrete value rather then returning -EINVAL but
this will need to be done on a per driver basis, where as this fix
at least gets us back to where things were before and thus restores
functionality on devices where this was lost due to
gpio_set_debounce_timeout() errors.

Commit 0b9902c1fcc5 ("s390/qeth: fix deadlock during recovery") removed
taking discipline_mutex inside qeth_do_reset(), fixing potential
deadlocks. An error path was missed though, that still takes
discipline_mutex and thus has the original deadlock potential.
Intermittent deadlocks were seen when a qeth channel path is configured
offline, causing a race between qeth_do_reset and ccwgroup_remove.
Call qeth_set_offline() directly in the qeth_do_reset() error case and
then a new variant of ccwgroup_set_offline(), without taking
discipline_mutex.

Problem: qeth_close_dev_handler is a worker that tries to acquire
card->discipline_mutex via drv->set_offline() in ccwgroup_set_offline().
Since commit b41b554c1ee7
("s390/qeth: fix locking for discipline setup / removal")
qeth_remove_discipline() is called under card->discipline_mutex and
cancels the work and waits for it to finish.
STOPLAN reception with reason code IPA_RC_VEPA_TO_VEB_TRANSITION is the
only situation that schedules close_dev_work. In that situation scheduling
qeth recovery will also result in an offline interface, when resetting the
isolation mode fails, if the external switch is still set to VEB.
And since commit 0b9902c1fcc5 ("s390/qeth: fix deadlock during recovery")
qeth recovery does not aquire card->discipline_mutex anymore.
So we accept the longer pathlength of qeth_schedule_recovery in this
error situation and re-use the existing function.
As a side-benefit this changes the hwtrap to behave like during recovery
instead of like during a user-triggered set_offline.

When qeth_set_online() calls qeth_clear_working_pool_list() to roll
back after an error exit from qeth_hardsetup_card(), we are at risk of
accessing card->qdio.in_q before it was allocated by
qeth_alloc_qdio_queues() via qeth_mpc_initialize().
qeth_clear_working_pool_list() then dereferences NULL, and by writing to
queue->bufs[i].pool_entry scribbles all over the CPU's lowcore.
Resulting in a crash when those lowcore areas are used next (eg. on
the next machine-check interrupt).
Such a scenario would typically happen when the device is first set
online and its queues aren't allocated yet. An early IO error or certain
misconfigs (eg. mismatched transport mode, bad portno) then cause us to
error out from qeth_hardsetup_card() with card->qdio.in_q still being
NULL.
Fix it by checking the pointer for NULL before accessing it.
Note that we also have (rare) paths inside qeth_mpc_initialize() where
a configuration change can cause us to free the existing queues,
expecting that subsequent code will allocate them again. If we then
error out before that re-allocation happens, the same bug occurs.

During the v5.13 cycle we updated the SPI subsystem to generate OF style
modaliases for SPI devices, replacing the old Linux style modalises we
used to generate based on spi_device_id which are the DT style name with
the vendor removed. Unfortunately this means that we start only
reporting OF style modalises and not the old ones and there is nothing
that ensures that drivers list every possible OF compatible string in
their OF ID table. The result is that there are systems which have been
relying on loading modules based on the old style that are now broken,
as found by Russell King with spi-nor on Macchiatobin.
spi-nor is a particularly problematic case for this, it only lists a
single generic DT compatible jedec,spi-nor in the driver but supports a
huge raft of device specific compatibles, with a large set of part
numbers many of which are offered by multiple vendors. Russell's
searches of upstream device trees has turned up examples with vendor
names written in non-standard ways too. To make matters worse up until
8ff16cf77ce3 ("Documentation: devicetree: m25p80: add "nor-jedec"
binding") the generic compatible was not part of the binding so there
are device trees out there written to that binding version which don't
list it all. The sheer number of parts supported together with our
previous approach of ignoring the vendor ID makes robustly fixing this
by adding compatibles to the spi-nor driver seem problematic, the
current DT binding document does not list all the parts supported by the
driver at the minute (further patches will fix this).
I've also investigated supporting both formats of modalias
simultaneously but that doesn't seem possible, especially without
breaking our userspace ABI which is obviously not viable.
Instead revert the relevant changes for now:
e09f2ab8eecc ("spi: update modalias_show after of_device_uevent_modalias support")
3ce6c9e2617e ("spi: add of_device_uevent_modalias support")
This will unfortunately mean that any system which had started having
modules autoload based on the OF compatibles for drivers that list
things there but not in the spi_device_ids will now not have those
modules load which is itself a regression. Since it affects a narrower
time window and the particularly problematic spi-nor driver may be
critical to system boot on smaller systems this seems the best of a
series of bad options. I will start an audit of SPI drivers to identify
and fix cases where things won't autoload using spi_device_id, this is
not great but seems to be the best way forward that anyone has been able
to identify.
Thanks to Russell for both his report and the additional diagnostic and
analysis work he has done here, the detailed research above was his
work.

Some devices, even non convertible ones, can send incorrect
SW_TABLET_MODE reports.
Add an allow list and accept such reports only from devices in it.

When DELL_WMI=y, DELL_WMI_PRIVACY=y, and LEDS_TRIGGER_AUDIO=m, there
is a linker error since the LEDS trigger code is built as a loadable
module. This happens because DELL_WMI_PRIVACY is a bool that depends
on a tristate (LEDS_TRIGGER_AUDIO=m), which can be dangerous.
ld: drivers/platform/x86/dell/dell-wmi-privacy.o: in function `dell_privacy_wmi_probe':
dell-wmi-privacy.c:(.text+0x3df): undefined reference to `ledtrig_audio_get'
