Subject: [PATCH v4 0/2] drm/panfrost: drm_gem_map_offset() helper

Panfrost has a re-implementation of drm_gem_dumb_map_offset() with an
extra bug regarding the handling of imported buffers. However we don't
really want Panfrost calling _dumb functions because it's not a KMS
driver.

This series renames drm_gem_dumb_map_offset() to drop the '_dumb' and
updates Panfrost to use it rather than it's own implementation.

Previous versions:

v3: https://lore.kernel.org/lkml/20190520092306.27633-1-steven.price@arm.com
Changes since v3:
 * Add a comment to drm_gem_map_offset() explaining that it can be used
   with shmem clients as well as dumb clients.

v2: https://lore.kernel.org/lkml/20190516141447.46839-1-steven.price@arm.com/
Changes since v2:
 * Drop the shmem helper

v1: https://lore.kernel.org/lkml/20190513143244.16478-1-steven.price@arm.com/
Changes since v1:
 * Rename drm_gem_dumb_map_offset to drop _dumb
 * Add a shmem helper

Steven Price (2):
  drm/gem: Rename drm_gem_dumb_map_offset() to drm_gem_map_offset()
  drm/panfrost: Use drm_gem_map_offset()
