IF_ENABLED(CONFIG_FOO, ptr) evaluates to (ptr) if CONFIG_FOO is set to 'y' or 'm', NULL otherwise. The (ptr) argument must be a pointer. The IF_ENABLED() macro can be very useful to help GCC drop dead code.
Looks great! Thanks a lot for getting this sorted.

I can apply this with the other patch to the pinctrl subsystem if Arnd or someone else who is good at KConfig provides an ACK.
Yes, please do. Acked-by: Arnd Bergmann <arnd@arndb.de>
