Subject: drm/omap: gem: Switch to gem_free_object_unlocked()
Git-commit: f8466184bd5b5c21eb6196cd0e44668725a2e47a
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

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.
This is already protected by the separate omapdrm->list_lock, which
means that struct_mutex is not needed by omapdrm. We can switch to
gem_free_object_unlocked()
