drm/armada: use unlocked gem unreferencing
For drm_gem_object_unreference callers are required to hold dev->struct_mutex, which these paths don't. Enforcing this requirement has become a bit more strict with commit ef4c6270bf2867e2f8032e9614d1a8cfc6c71663 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Oct 15 09:36:25 2015 +0200 drm/gem: Check locking in drm_gem_object_unreference Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
