Subject: [PATCH AUTOSEL 6.1 29/29] HID: Ignore battery for ELAN touchscreens 2F2C and 4116
From: Louis Dalibard <ontake@...ake.dev>
[ Upstream commit a3a5a37efba11b7cf1a86abe7bccfbcdb521764e ]
At least ASUS Zenbook 14 (2023) and ASUS Zenbook 14 Pro (2023) are affected.
The touchscreen reports a battery status of 0% and jumps to 1% when a
stylus is used.
The device ID was added and the battery ignore quirk was enabled for it.
[jkosina@...e.com: reformatted changelog a bit]
