You can say it to any cleanup work that starts from the baby steps.

My main goal is to get rid from kernel.h in the _headers_ first.
The secondary goal as discussed with Jonathan to have IIO subsystem
be cleaned up from kernel.h (meaning C files as well) at some point.

FWIW, I have started kernel.h cleanup due to impossibility to
make bitmap_*alloc() being static inline.
