linux.git/drivers/input, branch v5.11.8

Input: applespi - don't wait for responses to commands indefinitely.

2021-03-17T16:11:32+00:00

[ Upstream commit 0ce1ac23149c6da939a5926c098c270c58c317a0 ]

The response to a command may never arrive or it may be corrupted (and
hence dropped) for some reason. While exceedingly rare, when it did
happen it blocked all further commands. One way to fix this was to
do a suspend/resume. However, recovering automatically seems like a
nicer option. Hence this puts a time limit (1 sec) on how long we're
willing to wait for a response, after which we assume it got lost.

Input: i8042 - add ASUS Zenbook Flip to noselftest list

2021-03-04T11:15:18+00:00

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.

Input: joydev - prevent potential read overflow in ioctl

2021-03-04T11:15:18+00:00

commit 182d679b2298d62bf42bb14b12a8067b8e17b617 upstream.

The problem here is that "len" might be less than "joydev->nabs" so the
loops which verfy abspam[i] and keypam[] might read beyond the buffer.

Input: st1232 - fix NORMAL vs. IDLE state handling

2021-03-04T11:15:04+00:00

[ Upstream commit 1bff77f41a805b16b5355497c217656711601282 ]

NORMAL (0x0) and IDLE (0x4) are really two different states.  Hence you
cannot check for both using a bitmask, as that checks for IDLE only,
breaking operation for devices that are in NORMAL state.

Fix the wait function to report either state as ready.

Input: st1232 - add IDLE state as ready condition

2021-03-04T11:15:03+00:00

[ Upstream commit 6524d8eac258452e547f8a49c8a965ac6dd8a161 ]

The st1232 can switch from NORMAL to IDLE state after the configured
idle time (by default 8 s). If the st1232 is not reset during probe, it
might already be ready but in IDLE state. Since it does not enter NORMAL
state in this case, probe fails.

Fix the wait function to report the IDLE state as ready, too.
