Subject[PATCH] Add HID's to hid-microsoft driver of Surface Type/Touch Cover 2 to fix bug
The below patch fixes a bug 64811
(https://bugzilla.kernel.org/show_bug.cgi?id=64811) of the Microsoft
Surface Type/Touch cover 2 devices being detected as a multitouch
device.
The fix adds the HID of the two devices to hid-microsoft driver. This
ensures that hid-input will eventually be used for the device and not
hid-multitouch.
