Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.
In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"

We hit the problem with below sequence:
- ci_udc_vbus_session() update vbus_active flag and ci->driver
is valid,
- before calling the ci_hdrc_gadget_connect(),
usb_gadget_udc_stop() is called by application remove gadget
driver,
- ci_udc_vbus_session() will contine do ci_hdrc_gadget_connect() as
gadget_ready is 1, so udc interrupt is enabled, but ci->driver is
NULL.
- USB connection irq generated but ci->driver is NULL.
As udc irq only should be enabled when gadget driver is binded, so
add spinlock to protect the usb irq enable for vbus session handling.

Intel Ice Lake has two xHCI controllers one on PCH and the other as part
of the CPU itself. The latter is also part of the so called Type C
Subsystem (TCSS) sharing ACPI power resources with the PCIe root ports
and the Thunderbolt controllers. In order to put the whole TCSS block
into D3cold the xHCI needs to be runtime suspended as well when idle.
For this reason allow runtime PM as default for Ice Lake TCSS xHCI
controller.

Patch "USB: HCD: support giveback of URB in tasklet context"[1]
introduced giveback of urb in tasklet context. [1] This patch was
applied to ehci but not xhci. [2] This patch significantly reduces
the hard irq time of xhci. Especially for uvc driver, the hard irq
including the uvc completion function runs quite long but applying
this patch reduces the hard irq time of xhci.
I have tested four SS devices to check if performance degradation
occurs when urb completion functions run in the tasklet context.
As a result of the test, all devices works well and shows very
similar performance with the upstream kernel. Moreover, usb ethernet
adapter show better performance than the upstream kernel about 5% for
RX and 2% for TX. Four SS devices is as follows.
SS devices for test
1. WD My Passport 2TB (external hard drive)
2. Sandisk Ultra Flair USB 3.0 32GB
3. Logitech Brio webcam
4. Iptime 1gigabit ethernet adapter (Mediatek RTL8153)

2. Mass storage (flash memory) performance test
- run below command 10 times and compute the average performance
dd if=/dev/sdN iflag=direct of=/dev/null bs=1G count=1
3. Webcam streaming performance test
- run simple capture program and get the average frame rate per second
- capture 1500 frames
- program link

- video resolution : 4096 X 2160 (4K) at 30 or 24 fps
- device (Logitech Brio) spec url for the highest resolution and fps
https://support.logitech.com/en_gb/product/brio-stream/specs
4. USB Ethernet adapter performance test
- directly connect two linux machines with ethernet cable
- run pktgen of linux kernel and send 1500 bytes packets
- run vnstat to measure the network bandwidth for 180 seconds

On some situations, the software handles TRB events slower
than adding TRBs, then xhci_handle_event can't return zero
long time, the xHC will consider the event ring is full,
and trigger "Event Ring Full" error, but in fact, the software
has already finished lots of events, just no chance to
update ERDP (event ring dequeue pointer).
In this commit, we force update ERDP if half of TRBS_PER_SEGMENT
events have handled to avoid "Event Ring Full" error.

These are the Foxconn-branded variants of the Dell DW5821e modules,
same USB layout as those. The device exposes AT, NMEA and DIAG ports

Smatch reported that nents is not initialized and used in
stub_recv_cmd_submit(). nents is currently initialized by sgl_alloc()
and used to allocate multiple URBs when host controller doesn't
support scatter-gather DMA. The use of uninitialized nents means that
buf_len is zero and use_sg is true. But buffer length should not be
zero when an URB uses scatter-gather DMA.
To prevent this situation, add the conditional that checks buf_len
and use_sg. And move the use of nents right after the sgl_alloc() to
avoid the use of uninitialized nents.
If the error occurs, it adds SDEV_EVENT_ERROR_MALLOC and stub_priv
will be released by stub event handler and connection will be shut
down.

Drop the redundant port open flag and corresponding checks. USB serial
core will not call any of these driver callbacks for a closed port, and the
write URBs are stopped at close().

Drop read-urb check which is always false from completion the callback.
The driver read-urb pointer is set at every open and is never cleared.
