The above comments are more important but why does this mix defined and
IS_ENABLED? Couldn't they both use defined (and preferably with the
optional brackets around the CONFIG_ symbol).
No, always use IS_ENABLED() for tristates when you want to match 'y' or
'm'.
Oops.
Actually it was the mis-match in the original code that attracted my
attention (defined on one side, IS_ENABLED() on the other)... I'd be
happier if both used the same approach.
Daniel.
