Subject: HID: uclogic: Disable pen usage for Huion keyboard interfaces
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4c60bc7d1f2a908f53260bc4a0831b3ea204f327;p=linux.git

HID: uclogic: Disable pen usage for Huion keyboard interfaces

Disable pen usage inputs for Huion interfaces reporting on-the-frame
buttons. We don't want to change those, as they mostly work, but we want
to avoid creation of a mute pen interface, confusing to users.
