Input: zhenhua - ensure we have BITREVERSE

2015-10-28T15:38:31+00:00

commit d3b367bc26ea2e07a83fe73f0ccbddd729cb1f9a upstream.

It uses bitrev8(), so it must ensure that lib/bitrev.o gets included in
vmlinux.

Input: omap4-keypad - fix memory leak

2015-10-28T15:38:30+00:00

commit d79bdc7f004404204a6ac07785f8d6717070ecdb upstream.

If omap4_keypad_parse_dt() fails we returned the error code but we
missed releasing keypad_data.

Input: serio - fix blocking of parport

2015-10-28T15:38:30+00:00

commit 1a5e251996e1b602f2ddc9261ee9de0ca1875bfa upstream.

If parkbd_allocate_serio() fails to allocate memory we are releasing the
parport but we missed unregistering the device. As a result this device
with exclusive access to that parport remains registered. And no other
device will be able to use that parport even though this driver has
failed to load.

Input: psmouse - add small delay for IBM trackpoint pass-through mode

2015-10-28T15:38:29+00:00

commit 66bc2f51ef7deabc8b8f3baa98ae64b65e5e973a upstream.

There are trackpoint devices that fail to respond to the PS2 command
PSMOUSE_CMD_GETID if immediately queried after the parent device is
deactivated. Add a small delay for the hardware to get in a sane state
before sending any PS2 commands.

One example of such a system is:
Lenovo ThinkPad X120e, model 30515QG

Input: evdev - do not report errors form flush()

2015-09-30T09:00:05+00:00

commit eb38f3a4f6e86f8bb10a3217ebd85ecc5d763aae upstream.

We've got bug reports showing the old systemd-logind (at least
system-210) aborting unexpectedly, and this turned out to be because
of an invalid error code from close() call to evdev devices.  close()
is supposed to return only either EINTR or EBADFD, while the device
returned ENODEV.  logind was overreacting to it and decided to kill
itself when an unexpected error code was received.  What a tragedy.

The bad error code comes from flush fops, and actually evdev_flush()
returns ENODEV when device is disconnected or client's access to it is
revoked. But in these cases the fact that flush did not actually happen is
not an error, but rather normal behavior. For non-disconnected devices
result of flush is also not that interesting as there is no potential of
data loss and even if it fails application has no way of handling the
error. Because of that we are better off always returning success from
evdev_flush().

Also returning EINTR from flush()/close() is discouraged (as it is not
clear how application should handle this error), so let's stop taking
evdev->mutex interruptibly.

Input: usbtouchscreen - avoid unresponsive TSC-30 touch screen

2015-08-19T06:36:39+00:00

commit 968491709e5b1aaf429428814fff3d932fa90b60 upstream.

This patch fixes a problem in the usbtouchscreen driver for DMC TSC-30
touch screen.  Due to a missing delay between the RESET and SET_RATE
commands, the touch screen may become unresponsive during system startup or
driver loading.

According to the DMC documentation, a delay is needed after the RESET
command to allow the chip to complete its internal initialization. As this
delay is not guaranteed, we had a system where the touch screen
occasionally did not send any touch data. There was no other indication of
the problem.

The patch fixes the problem by adding a 150ms delay between the RESET and
SET_RATE commands.

Input: elantech - fix detection of touchpads where the revision matches a known rate

2015-06-23T12:55:11+00:00

commit 5f0ee9d17aae628b22be86966471db65be21f262 upstream.

Make the check to skip the rate check more lax, so that it applies
to all hw_version 4 models.

This fixes the touchpad not being detected properly on Asus PU551LA
laptops.

Input: elantech - fix semi-mt protocol for v3 HW

2015-06-03T09:33:14+00:00

commit 3c0213d17a09601e0c6c0ae0e27caf70d988290f upstream.

When the v3 hardware sees more than one finger, it uses the semi-mt
protocol to report the touches. However, it currently works when
num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1
finger as if num_fingers was 1.

This confuses userspace which knows how to deal with extra fingers
when all the slots are used, but not when some are missing.
