commit daa58c8eec0a65ac8e2e77ff3ea8a233d8eec954 upstream.

The Zenbook Flip entry that was added overwrites a previous one
because of a typo:

In file included from drivers/input/serio/i8042.h:23,
                 from drivers/input/serio/i8042.c:131:

drivers/input/serio/i8042-x86ia64io.h:591:28: note: (near initialization for 'i8042_dmi_noselftest_table[0].matches')

Add the missing separator between the two.

[ Upstream commit 69d5ff3e9e51e23d5d81bf48480aa5671be67a71 ]

The driver registers an interrupt handler in _probe, but didn't configure
them until later when the _open function is called. In between, the keypad
can fire an IRQ due to touchpad activity, which the handler ignores. This
causes the kernel to disable the interrupt, blocking the keypad from
working.

Fix this by disabling interrupts before registering the handler.
Additionally, disable them in _close, so that they're only enabled while
open.

commit b5d6e7ab7fe7d186878142e9fc1a05e4c3b65eb9 upstream.

After commit 77b425399f6d ("Input: i8042 - use chassis info to skip
selftest on Asus laptops"), all modern Asus laptops have the i8042
selftest disabled. It has done by using chassys type "10" (laptop).

The Asus Zenbook Flip suffers from similar suspend/resume issues, but
it _sometimes_ work and sometimes it doesn't. Setting noselftest makes
it work reliably. In this case, we need to add chassis type "31"
(convertible) in order to avoid selftest in this device.

loops which verfy abspam[i] and keypam[] might read beyond the buffer.

There is a fork of this driver on GitHub [0] that has been updated

Merge those into the mainline driver, so the out-of-tree fork is not
needed for users of those devices anymore.

<title>Input: uinput - avoid FF flush when destroying device</title>

<id>urn:sha1:0cd7ca78a35976956292daf32bf7831e6c18753d</id>
<content type='text'>
commit e8b95728f724797f958912fd9b765a695595d3a6 upstream.

Normally, when input device supporting force feedback effects is being
destroyed, we try to "flush" currently playing effects, so that the
physical device does not continue vibrating (or executing other effects).
Unfortunately this does not work well for uinput as flushing of the effects
deadlocks with the destroy action:

- if device is being destroyed because the file descriptor is being closed,
  then there is noone to even service FF requests;

- if device is being destroyed because userspace sent UI_DEV_DESTROY,
  while theoretically it could be possible to service FF requests,
  userspace is unlikely to do so (they'd need to make sure FF handling
  happens on a separate thread) even if kernel solves the issue with FF
  ioctls deadlocking with UI_DEV_DESTROY ioctl on udev-&gt;mutex.

To avoid lockups like the one below, let's install a custom input device
flush handler, and avoid trying to flush force feedback effects when we
destroying the device, and instead rely on uinput to shut off the device
properly.
