Yes, the build would break only if you change Kconfig/Makefile to
actually build it.  The patch does not enable the build of the driver
in the patch.

Understood.  Do you want me to resend the gpio-mxs and gpio-mxc patch
sets for that?  Or can I follow the practice you and Russell
suggested in the future posts?  I have learnt the lesson.

Do I need to re-spin the patch set to fix it, or maintainer (you or
Sascha) can help to fix it up?

BTW, do you and Sascha get the agreement on which tree the gpio-mxs
and gpio-mxc should go through?
