Thanks, that makes perfect sense.

I became intrigued by the one-line summary, which seemed to suggest
(according to my interpretation) that including kernel.h is a Real Bad
Thing.

But basically all you wanted to say was:

    drm: shmobile: Reduce include dependencies

and:

    This file doesn't need everything provided by <linux/kernel.h>.
    All it needs are some types, which are provided by <linux/types.h>.

Right?

BTW, <drm/drm_mode.h> already includes <linux/types.h>, but not relying
on implicit includes is indeed a good thing.
