I found this in section 12, about Macros, Enums and RTL in both

It seems this

"""
CAPITALIZED macro names are appreciated but macros resembling functions may be named in lower case.
"""

It's just a suggestion, not a big deal. In general, if checkpatch.pl
is not complaining, it's not worth the trouble.

So let's skip this fix.

Thanks a lot!

Maybe you can see if these macros can be converted to static inline
functions. Macros don't provide any type checking.
