[PATCH v1 3/7] drm: move drm_can_sleep() to drm_util.h

Wed Dec 26 21:03:49 UTC 2018

Move drm_can_sleep() out of drmP.h to allow users
to get rid of the drmP.h include.

There was no header file that was a good match for this helper function.
So add this to drm_util with the relevant includes.

Add include of drm_util.h to all users.
