The series focuses on providing a user readable error value on a failure
in drm_atomic_ioctl(). Usually -EINVAL is returned in most of the error
cases and it is difficult for the user to decode the error and get to
know the real cause for the error. If user gets to know the reason for
the error then corrective measurements can be taken up.
TODO: driver specific error codes are to be added and will be done in
the follow-up patches.
