Happy to keep the Reviewed-by there, just add 'def' in the right place and
you're sweet.

This was one of (if not the only) the *real* issues I noticed with the series.
As discussed, (and do double check) but #if expects a condition - which in this
case is working because [AC_DEFINE(MTD_SUPPORT, 1, [Enable MTD support])] but
I'm pretty sure what you really want is #ifdef since the MACRO being def‏ined
is what you really want to test for.
