ctype.h provides tolower() macro specifically for the cases that might be architecture-optimised. Using __tolower(), which is internal implementation, needs a good justification, as this driver is the only user of that and there is no evidence it's required.
Note, currently it's no difference as the macro always defined to the internal implementation, but it might change in the future.
