[PATCH] Input: psmouse - disable non-wakeup armed PS/2 mouse when s2dile
From: Aaron Ma
Date: Tue Aug 10 2021 - 23:50:31 EST
After commit 684bec1092b6 ("Input: i8042 - enable keyboard wakeups by
default when s2idle is used"), kdb is enabled to wakeup laptops.
Kbd fails to wakeup when touchpad/trackpoint is used on ThinkPad.
The touchpad is not set to wakeup, and it shares buffer with kbd.
Send disable command to PS/2 mouse when s2idle, make it clean for
kdb to wakeup.
Enable PS/2 mouse when wakeup enabled.
