2019-06-26HID: intel-ish-hid: fix wrong driver_data usageHyungwoo Yang
Currently, in suspend() and resume(), ishtp client drivers are using driver_data to get "struct ishtp_cl_device" object which is set by bus driver. It's wrong since the driver_data should not be owned bus. driver_data should be owned by the corresponding ishtp client driver. Due to this, some ishtp client driver like cros_ec_ishtp which uses its driver_data to transfer its data to its child doesn't work correctly. So this patch removes setting driver_data in bus drier and instead of using driver_data to get "struct ishtp_cl_device", since "struct device" is embedded in "struct ishtp_cl_device", we introduce a helper function that returns "struct ishtp_cl_device" from "struct device".

2019-06-26HID: logitech-dj: Fix forwarding of very long HID++ reportsHans de Goede
The HID++ spec also defines very long HID++ reports, with a reportid of 0x12. The MX5000 and MX5500 keyboards use 0x12 output reports for sending messages to display on their buildin LCD. Userspace (libmx5000) supports this, in order for this to work when talking to the HID devices instantiated for the keyboard by hid-logitech-dj, we need to properly forward these reports to the device. This commit fixes logi_dj_ll_raw_request not forwarding these reports.

The c52f nano receiver is a mouse only receiver. This means that it needs some special handling compared to the c534 nano receiver: 1) It sends unnumbered mouse reports with a size of 8 bytes, so we need to extend the unnumbered mouse report handling to support reports upto 8 bytes large 2) It mouse reports have the same high-resolution format as those from the gaming mouse receivers 3) It can report consumer/multimedia buttons on its second interface, since this is a mouse-only receiver these must be forwarded to the mouse child device and not to the keyboard child-device (which will not exist) Link: https://bugzilla.kernel.org/show_bug.cgi?id=203619 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>

2019-05-22HID: multitouch: handle faulty Elo touch deviceBenjamin Tissoires
Since kernel v5.0, one single win8 touchscreen device failed. And it turns out this is because it reports 2 InRange usage per touch. It's a first, and I *really* wonder how this was allowed by Microsoft in the first place. But IIRC, Breno told me this happened *after* a firmware upgrade... Anyway, better be safe for those crappy devices, and make sure we have a full slot before jumping to the next. This won't prevent all crappy devices to fail here, but at least we will have a safeguard as long as the contact ID and the X and Y coordinates are placed in the report after the grabage.

2019-05-18treewide: prefix header search paths with $(srctree)/Masahiro Yamada
Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter").

2019-05-17HID: wacom: Sync INTUOSP2_BT touch state after each frame if necessaryJason Gerecke
The Bluetooth interface of the 2nd-gen Intuos Pro batches together four independent "frames" of finger data into a single report. Each frame is essentially equivalent to a single USB report, with the up-to-10 fingers worth of information being spread across two frames. At the moment the driver only calls `input_sync` after processing all four frames have been processed, which can result in the driver sending multiple updates for a single slot within the same SYN_REPORT. This can confuse userspace, so modify the driver to sync more often if necessary (i.e., after reporting the state of all fingers).

2019-05-17HID: wacom: Correct button numbering 2nd-gen Intuos Pro over BluetoothJason Gerecke
The button numbering of the 2nd-gen Intuos Pro is not consistent between the USB and Bluetooth interfaces. Over USB, the HID_GENERIC codepath enumerates the eight ExpressKeys first (BTN_0 - BTN_7) followed by the center modeswitch button (BTN_8). The Bluetooth codepath, however, has the center modeswitch button as BTN_0 and the the eight ExpressKeys as BTN_1 - BTN_8. To ensure userspace button mappings do not change depending on how the tablet is connected, modify the Bluetooth codepath to report buttons in the same order as USB. To ensure the mode switch LED continues to toggle in response to the mode switch button, the `wacom_is_led_toggled` function also requires a small update.

2019-05-17HID: wacom: Send BTN_TOUCH in response to INTUOSP2_BT eraser contactJason Gerecke
The Bluetooth reports from the 2nd-gen Intuos Pro have separate bits for indicating if the tip or eraser is in contact with the tablet. At the moment, only the tip contact bit controls the state of the BTN_TOUCH event. This prevents the eraser from working as expected. This commit changes the driver to send BTN_TOUCH whenever either the tip or eraser contact bit is set.

2019-05-17HID: wacom: Don't report anything prior to the tool entering rangeJason Gerecke
If the tool spends some time in prox before entering range, a series of events (e.g. ABS_DISTANCE, MSC_SERIAL) can be sent before we or userspace have any clue about the pen whose data is being reported. We need to hold off on reporting anything until the pen has entered range. Since we still want to report events that occur "in prox" after the pen has *left* range we use 'wacom-tool[0]' as the indicator that the pen did at one point enter range and provide us/userspace with tool type and serial number information.

2019-05-17HID: wacom: Don't set tool type until we're in rangeJason Gerecke
The serial number and tool type information that is reported by the tablet while a pen is merely "in prox" instead of fully "in range" can be stale and cause us to report incorrect tool information. Serial number, tool type, and other information is only valid once the pen comes fully in range so we should be careful to not use this information until that point. In particular, this issue may cause the driver to incorectly report BTN_TOOL_RUBBER after switching from the eraser tool back to the pen.

2019-05-09HID: rmi: Use SET_REPORT request on control endpoint for Acer Switch 3 and 5Tobias Auerochs
The touchpad on the cover keyboard for the Acer Switch 3 and 5 does not work as-is under Linux. Both devices have the same usb id for the cover keyboard. The kernel correctly assigns the hid-rmi driver to the device using usbhid for transport. Any attempts of hid-rmi to talk to the device using hid_hw_output_report fail however as usbhid does not have a working urbout due to the lack of any out endpoints. Looking through Wireshark usbmon recordings from the Windows Synaptics driver for this computer running inside of QEMU shows that it should be using SET_REPORT requests instead. This replaces the hid_hw_output_report in hid-rmi with a hid_hw_raw_request for this device, which is at least enough to enable the kernel to get working multi-touch input.

Note: this patch does not conflict with "fuse: Add FOPEN_STREAM to use stream_open()" that will be hopefully coming via FUSE tree, because fs/fuse/ uses new-style .read_iter/.write_iter, and for these accessors position is still passed as non-pointer kiocb.ki_pos . * tag 'stream_open-5.2' of https://lab.nexedi.com/kirr/linux: vfs: pass ppos=NULL to .read()/.write() of FMODE_STREAM files *: convert stream-like files from nonseekable_open -> stream_open dtlk: remove double call to nonseekable_open

I've verified each generated change manually - that it is correct to convert - and each other nonseekable_open instance left - that it is either not correct to convert there, or that it is not converted due to current stream_open.cocci limitations.

One can also recheck/review the patch via generating it with explanation comments included via $ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci SPFLAGS="-D explain" (*) This second group also contains cases with read/write deadlocks that stream_open.cocci don't yet detect, but which are still valid to convert to stream_open since ppos is not used. For example drivers/pci/switch/switchtec.c calls wait_for_completion_interruptible() in its .read, but stream_open.cocci currently detects only "wait_event*" as blocking.
