The CONFIG_ prefix is reserved for Kconfig options in Make and CPP
syntax.  CONFIG_MAGIC is a file local CPP identifier so strip the prefix
to apply to Kconfig's naming convention.

           ^^^^^
This is too general for a preprocessor symbol; how about
NOZOMI_CONFIG_MAGIC?

Okay, sounds much better than ``MAGIC''.  I will send a second version
of this patch.

Kind regards,
