A typical example of what comments shouldn't be:
case DRM_PLANE_TYPE_PRIMARY: /* primary */
Well, yes!, it's written just there, PRIMARY!

Making function to the similar things is very common in programming.
Let's do it once again.
Cairo being a drawing library, it can be used to do the rotation!

Clearly, someone tried to solve the following warning:
kms_rotation_crc.c:189:6: warning: no previous prototype for ‘check_plane_type’ [-Wmissing-prototypes]
Without really understanding what was the warning about. Make
check_plane_type() static and move it before its user to get rid of the forward
declaration.
