The GEM and PRIME related callbacks in struct drm_driver are deprecated in
favor of GEM object functions in struct drm_gem_object_funcs. This patchset
converts the remaining drivers to object functions and removes most of the
obsolete interfaces.
Patches #1 to #18 convert DRM drivers to GEM object
GEM object functions deprecate several similar callback interfaces in

The patch reorganizing the set_freq function made it so the gmu resume
doesn't always set the frequency, because a6xx_gmu_set_freq() exits early
when the frequency hasn't been changed. Note this always happens when
resuming GMU after recovering from a hang.
Use a simple workaround to prevent this

Currently it doesn't matter, since we free the ctx immediately. But
when we start refcnt'ing the ctx, we don't want old dangling list
entries to hang around.
