CVE-2022-48633
In the Linux kernel, the following vulnerability has been resolved:

drm/gma500: Fix WARN_ON(lock->magic != lock) error

psb_gem_unpin() calls dma_resv_lock() but the underlying ww_mutex
gets destroyed by drm_gem_object_release() move the
drm_gem_object_release() call in psb_gem_free_object() to after
the unpin to fix the below warning:
