The patch titled
drm: check return values in drm_version
has been removed from the -mm tree. Its filename was
drm-check-return-values-in-drm_version.patch
This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: drm: check return values in drm_version
From: Andres Salomon <dilinger@xxxxxxxxxxxxxxx>
In drm_version, actually check the results from function calls so that
we're not potentially passing garbage back to userspace.
