description:
Delete dead-as-a-doornail-in-a-dead-horse branch.

If dev_priv is null here, you're hosed to begin with, so the apparent
null pointer dereference in this branch is moot; also this is the old
drm code that we should maybe just delete altogether...

Potential null pointer dereference reported by Dr Silvio Cesare of
InfoSect.
