[PATCH 6.1 036/105] HID: Ignore battery for ELAN touchscreens 2F2C and 4116

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Louis Dalibard <ontake@xxxxxxxxxx>

[ 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.
