HID: wiimote: add MP quirks
Devices which have built-in motion plus ports don't need MP detection logic. The new WIIMOD_BUILTIN_MP modules sets the WIIPROTO_FLAG_BUILTIN_MP flag which disables polling for MP. Some other devices erroneously report that they support motion-plus. For these devices and all devices without extension ports, we load WIIMOD_NO_MP which sets WIIPROTO_FLAG_NO_MP. This effectively disables all MP detection logic. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
