HID: uclogic: merge hid-huion driver in hid-uclogic
Merge the hid-huion driver into hid-uclogic as all the devices supported by hid-huion are in fact UC-Logic devices. Signed-off-by: Nikolai Kondrashov <Nikolai.Kondrashov@redhat.com> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
