[PATCH 5/5] drm/omapdrm: Switch to gem_free_object_unlocked

[Daniel Vetter]

The only thing that omap_gem_free_object does that might need the
magic protection of struct_mutex (of keeping all objects alive if that
lock is held, even if the last reference is gone) is the mm_list
manipulation.

But that is already protected by the separate omapdrm->list_lock,
which means struct_mutex is an entirely internal lock for omapdrm.
Everything else is just releasing resources, which is all protected
already by the various subsystems and allocators.

To make this even more obvious we could do an
s/dev->struct_mutex/omapdrm->gem_lock/ like I've done for udl. But
since omapdrm is a lot bigger and a lot more active I'll refrain from
that - this is better done by omapdrm developers at some suitable time
in the future.
