This was reported over a week ago by the kbuild test robot and I've had
fixes for this (and an additional sparse warning) in my tree for a while
now. Interestingly everybody at Intel seems to have forgotten about this
driver after their patches got merged since nobody cared to respond.
I've now pushed out the patch that I had locally.
Thanks,
Thierry
