HID: Ignore battery for all ELAN I2C-HID devices
[ Upstream commit bcc31692a1d1e21f0d06c5f727c03ee299d2264e ]
Before this change there were 16 vid:pid based quirks to ignore the battery
reported by Elan I2C-HID touchscreens on various Asus and HP laptops.
And a report has been received that the 04F3:2A00 I2C touchscreen on
the HP ProBook x360 11 G5 EE/86CF also reports a non present battery.
Since I2C-HID devices are always builtin to laptops they are not battery
owered so it should be safe to just ignore the battery on all Elan I2C-HID
devices, rather then adding a 17th quirk for the 04F3:2A00 touchscreen.
As reported in the changelog of commit a3a5a37efba1 ("HID: Ignore battery
for ELAN touchscreens 2F2C and 4116"), which added 2 new Elan touchscreen
quirks about a month ago, the HID reported battery seems to be related
to a stylus being used. But even when a stylus is in use it does not
properly report the charge of the stylus battery, instead the reported
battery charge jumps from 0% to 1%. So it is best to just ignore the
HID battery.
