This patch series renames all CMA helpers to DMA helpers - considering the
hierarchy of APIs (mm/cma -> dma -> gem/fb dma helpers) calling them DMA
helpers seems to be more applicable.

Additionally, commit e57924d4ae80 ("drm/doc: Task to rename CMA helpers")
requests to rename the CMA helpers and implies that people seem to be confused
about the naming.

The patches are compile-time tested building a x86_64 kernel with
`make allyesconfig && make drivers/gpu/drm`.

Changes in v2:
  - Fixed up comments for consistent memory/address classification
    (DMA-contiguous)
  - Added a patch to rename struct drm_gem_dma_object.{paddr => dma_addr}

Changes in v3:
  - Use a ccoccinelle script for
    "drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr}" for fixing
    up missing drivers and compile-test on x86_64, arm and arm64.

Changes in v4:
  - Rebased all patches on drm-misc/drm-misc-next.

Changes in v5:
  - Rebase of v4, meanwhile some merge conflicts came up on
    drm-misc/drm-misc-next.

Changes in v6:
  - Added a patch to remove unused include occurances of drm_fb_cma_helper.h
    in various drivers.

Danilo Krummrich (5):
  drm/fb: remove unused includes of drm_fb_cma_helper.h
  drm/fb: rename FB CMA helpers to FB DMA helpers
  drm/gem: rename GEM CMA helpers to GEM DMA helpers
  drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr}
  drm/todo: remove task to rename CMA helpers
