Subject: [PATCH 4/5] HID: multitouch: specify that Apple Touch Bar is direct
|
|
|
|
Currently the driver determines the device type based on the
|
|
application, but this value is not reliable on Apple Touch Bar, where
|
|
the application is HID_DG_TOUCHPAD even though this device is direct,
|
|
so add a quirk for the same.
