Subject: [PATCH] HID: Ignore battery for Elan touchscreen on Asus UX550VE
Git-commit: 14902f8961dca9c66bf190f7b1583767c97a4197
Patch-mainline: v5.16-rc5
References: git-fixes
Battery status is reported for the Asus UX550VE touchscreen even though
it does not have a battery. Prevent it from always reporting the
battery as low.
