Apologies, I forgot to use --strict. It's not pretty indeed. I've
fixed most of the problems reported ; a few are more tricky or would
require extra cleanup patches like converting e.g. uint32_t to u32
when adding a member to a struct, which would make sense if we convert
all members of the struct (or better, the whole driver) separately.
Hopefully these can be overlooked for the time being.
