- drm_gem_prime_import_dev increases the per-device import memory
counter
* Most drivers use it.
* drivers that have a (*gem_prime_import) callback will need
additional changes, which can be done if everyone likes the
overall RFC.
- drm_prime_gem_destroy decreases the per-device import memory
counter.
* All drivers seem to use it?
