I've discussed this a couple of weeks back with Benjamin Tissoires, and this patch would break the special keys (mute, brightness up/down, keyboard backlight up/down and play/pause). The recommended way to fix this was to move multi-touch processing into the Microsoft driver, so that it would handle the trackpad's multi- touch events. You should be able to do this by carefully picking up the handling code from hid-multitouch, or do something similar to what's done in hid- wacom, which has the same problem as the Type Cover handling. Can you confirm that this does indeed break those special keys? If it does, it's a NAK from my side.
