+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.
