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.
