Thanks!

Those >80char WARNs are mostly macro "\" on col 81. That is afaik ok.
Maybe that should be changed in checkpatch as well.

The error is false possitive. It is again in macro, checkpatch thinks it
is a function and yells about "{" on the same line. However it is a
struct initialization so in that case it is ok.

I agree.
