Commit msg still a bit misleading, but meh, pushed 1-3 anyway. Thanks.

I did wrap this line while applying since it was trivial and made
checkpatch happy.

I see one other valid checkpatch complaint in the report (some alignment
fail in one of the later patches). The wm debug >80col warnings we can't
really fix without some refactoring or making the code look evem uglier
so imo ignore those.
