From: Peter Ujfalusi <peter.ujfal...@ti.com>

If we allocate the drm_device earlier we can just return the error code
without the need to use goto.
Do the unref of the drm_device as a last step when cleaning up. This will
make the drm_device available longer for us and makes sure that we only
free up the memory when all other cleanups have been already done.
