Thanks I'll add your Ack before moving this for-next and sorry for
not coordinating this before hand.

TBH I completely missed that the 2 other patches where under drivers/hid
since 90% or so of all surface stuff is under drivers/platform/surface
I sorta assumed all patches where for there. My bad, sorry.

(Note to self: Next time not only review the contents of the diff but
also look at the file-paths).

Regards,

Hans
