HID: Add Holtek USB ID 04d9:a0c2 ETEKCITY Scroll
The report descriptor for the HOLTEK USB ID 04d9:a0c2 (ETEKCITY Scroll T-140 Gaming Mouse) is set to a very large amount of consumer usages (2^16), exceeding HID_MAX_USAGES. Added id, bindings and comments for the mouse, added to hid_have_special_driver, and reduced the usage and logical maximums to 0x2fff, consistent with the other mice in the category. Tested on the hardware. Signed-off-by: John C. DeSilva <desilvjo@umich.edu> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
