Subject: usbtouchscreen: fix eGalax HID ignoring
From: Daniel Ritz <daniel.ritz-ml@xxxxxxxxxxxxxx>
Fix the eGalax/EETI HID device ignoring by adding a match for the protocol
too. This is what the marco USB_DEVICE_HID_CLASS() was supposed to do
anyways.
Devices confirmed to be real HID have the class set to HID and the
protocol set to 'mouse'. Some have HID class but protocol set to 'none'.
Those are not HID and should be driven by usbtouchscreen.
