This macro is never used, so it could just be removed, right?

Same with that one. Care to do that type of fixup instead please?

I don't see it being used anywhere, do you?

I don't see it being used anywhere, do you? Use 'git grep' to search
for it. Even better yet, remove it and rebuild the driver and see if it
breaks :)

Only if the code is not between #ifn?def / #endif...

Heh, fair enough, but it usually is a good sign if you do a build, along
with a search, that you are safe to remove something.
