[RFC PATCH 8/8] drm: trace memory import per DRM device

[Gurchetan Singh]

- 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?
