From 30a958526d2cc6df38347336a602479d048d92e7 Mon Sep 17 00:00:00 2001

Subject: [PATCH] drm: drop DRM_AUTH from PRIME_TO/FROM_HANDLE ioctls
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
As mentioned by Christian, for drivers which support only primary nodes
this changes the returned error from -EACCES into -EOPNOTSUPP/-ENOSYS.
For others, this check in particular will be a noop. So let's remove it
as suggested by Christian.
