This change is okay, just a comment for further possible cleanup.

Please, consider making driver use uXX/sXX types over uintXX_t/intXX_t
for the kernel-only code and the respective double underscore for ABI
data types (I'm not sure about firmware protocol, it's strictly speaking
an ABI, but sometimes we use internal types) — __uXX/__sXX.

Maybe not entire driver at once (can be tons of lines to change), but small
step first to check if the approach is correct.
