[PATCH 0/6] drm/lima: simplify driver by using more drm helpers

[Qiang Yu]

By using shared drm helpers:
1. drm_gem_objects_lookup
2. drm_gem_(un)lock_reservations
3. drm_gem_shmem_helpers
we can simplify lima driver a lot and benifit from updates to
these functions.

drm_gem_objects_lookup need a refine in order to be used by lima.

Note:
1. changes to panfrost and v3d are just compile tested.
2. patch series is based on drm-misc-next branch

Qiang Yu (6):
  drm/gem: refine drm_gem_objects_lookup
  drm/v3d: use drm_gem_objects_lookup
  drm/lima: use drm_gem_objects_lookup
  drm/lima: use drm_gem_shmem_helpers
  drm/lima: use drm_gem_(un)lock_reservations
  drm/lima: add __GFP_NOWARN flag to all dma_alloc_wc
