One more aside on top: One of the reasons I really like cocci is that it
also makes reviewing such large-scale refactorings easier. But I agree
that for this one here it would have been a bit more fuzz since matching
functions to add the struct intel_ringbuffer *ringbuf local variable is a
bit tricky to do.

Same goes for big sed patches - please add the precise sed filter to the
patch since reviewing that one is much less work than the resulting diff
;-)
