Subject: [PATCH AUTOSEL 4.19 3/7] Input: i8042 - add nomux quirk for Acer P459-G2-M

From: Esther Shimanovich <eshimanovich@...omium.org>

[ Upstream commit 335fe00319e030d481a54d5e0e68d50c5e672c0e ]

After the laptop lid is opened, and the device resumes from S3 deep
sleep, if the user presses a keyboard key while the screen is still black,
the mouse and keyboard become unusable.

Enabling this quirk prevents this behavior from occurring.
