Subject: [PATCH AUTOSEL 6.1 21/24] HID: Ignore battery for ELAN touchscreen 29DF on HP

From: Luka Guzenko <l.guzenko@....de>

[ Upstream commit ebebf05a4b06a1be49788ca0edf990de01c4b0d0 ]

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.
