Subject: Input: mark serio and i8042 as suspended when hibernating too
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ddaa43433dd77535e4e132787f199f58ce224f44;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Input: mark serio and i8042 as suspended when hibernating too

Serio ports are not being restarted any longer because resume operations
after hibernate do nothing, since the device has not been marked as
suspended. This happens because suspend is only considering the SUSPEND
event but not the FREEZE event.

Note that this driver has still to migrate to dev_pm_ops, but this fixes
this particular bug now.
