Re: [PATCH 1/2] HID: Use multitouch driver for Type Covers

I tested the patch again with xev and found that those "charm" keys
don't respond both on hid-microsoft and hid-multitouch, while other

Anyway, keys working with hid-microsoft also work with hid-multitouch,
so It's ready for merging, I think.
