HID: hid-input: Add parentheses to quell gcc warning

2016-09-29T09:14:04+00:00

commit 09a5c34e8d6b05663ec4c3d22b1fbd9fec89aaf9 upstream.

GCC reports a -Wlogical-not-parentheses warning here; therefore
add parentheses to shut it up and to express our intent more.

HID: multitouch: Add MT_QUIRK_NOT_SEEN_MEANS_UP to Surface Pro 3

2016-08-19T07:51:04+00:00

commit a80e803a2ae4efa5efbcfa97dcbbc48d15226cf9 upstream.

The firmware found in the touch screen of an SP3 is buggy and may miss
to send lift off reports for contacts. Try to work around that issue by
using MT_QUIRK_NOT_SEEN_MEANS_UP.

HID: i2c-hid: set power sleep before shutdown

2016-08-19T07:51:04+00:00

commit d9f448e3d71f3a703977196fa73be533b4b85adc upstream.

Add i2c_hid_shutdown for i2c-hid driver to send suspend cmd & free
irq before device shutdown.

Some HW design (i.e. Umaro, a chromebook model) is that the power to
i2c hid device won't down after device shutdown. Also the i2c-hid driver
do not send suspend cmd to the hid i2c device and free its irq before
shutdown.So if We touch the touchscreen or some other i2c hid device,
the power consumtion will be go up even when the device is in shutdown
state.

Though the root cause maybe a HW issue. But it seems that it is a
good pratice to set power sleep for i2c-hid device before shutdown.

HID: elo: kill not flush the work

2016-07-21T06:36:11+00:00

commit ed596a4a88bd161f868ccba078557ee7ede8a6ef upstream.

Flushing a work that reschedules itself is not a sensible operation. It needs
to be killed. Failure to do so leads to a kernel panic in the timer code.

HID: hiddev: validate num_values for HIDIOCGUSAGES, HIDIOCSUSAGES commands

2016-07-21T06:36:10+00:00

commit 93a2001bdfd5376c3dc2158653034c20392d15c5 upstream.

This patch validates the num_values parameter from userland during the
HIDIOCGUSAGES and HIDIOCSUSAGES commands. Previously, if the report id was set
to HID_REPORT_ID_UNKNOWN, we would fail to validate the num_values parameter
leading to a heap overflow.

HID: usbhid: enable NO_INIT_REPORTS quirk for Semico USB Keykoard2

2016-06-15T07:32:01+00:00

commit c14022bfd2eb2d2ece74a405dfbdb02a829c07bc upstream.

The device which identifies itself as a "USB Keykoard" (no typo)
with VID:PID 1a2c:0027 does not seem to be handling the reports
initialization very well.

This results in a "usb_submit_urb(ctrl) failed: -1" message from the
kernel when connected, and a delay before its initialization. It can
also cause the hang the system.

This patch adds the  quirk for this device, which causes the delay
to disappear. It is named as "USB Keykoard2" because the "USB Keykoard"
already exists.

HID: wiimote: Fix wiimote mp scale linearization

2016-06-15T07:32:01+00:00

commit d30596737e8e7b2f1235d7ba20592b8309e3af04 upstream.

The wiimote motion plus gyros use two scales to report fast and slow
rotation - below 440 deg/s uses 8192/440 units / deg/s, and above uses
8192/2000 units / deg/s.

Previously this driver attempted to linearize the two by scaling the fast
rate by 18 and the slow by 9, but this results in a scale of
8192*9/440 = ~167.564 for slow and 8192*18/2000 = 73.728 for fast.

Correct the fast motion scale factor so that both report ~167.564
units / deg/s
