[PATCH AUTOSEL 6.3 20/24] HID: Ignore battery for ELAN touchscreen on ROG Flow X13 GV301RA

[Sasha Levin]

From: weiliang1503 <weiliang1503@xxxxxxxxx>

[ Upstream commit 35903009dbde804a1565dc89e431c0f15179f054 ]

Ignore the reported battery level of the built-in touchscreen to suppress
battery warnings when a stylus is used. The device ID was added and the
battery ignore quirk was enabled.
