Subject: [PATCH] HID: Ignore battery for Elan touchscreen on Asus UX550VE
Date: Tue, 7 Dec 2021 13:10:53 +0100 [thread overview]
Message-ID: <20211207121053.136906-1-hdegoede@redhat.com> (raw)
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.
