HID: hid-input quirk for BTC 8193
BTC 8193 keyboard handles its scrollwheel in very non-standard way. It produces two non-standard usages for scrolling up and down, in both cases with postive value equaling to 1. We handle this by temporary mapping, which we then catch in quirk event handler, and remap to negative HWHEEL even in order to introduce correct behavior. Also the button requires special mapping, as it triggers standard-violating usage code. Reported in kernel.org bugzilla #9385 Reported-by: Kir Kolyshkin <kir@sacred.ru> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
