Subject: [PATCH] HID: Ignore battery for ELAN touchscreen 29DF on HP
Date: Fri, 20 Jan 2023 23:37:41 +0100 [thread overview]
Message-ID: <20230120223741.3007-1-l.guzenko@web.de> (raw)
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.
