[PATCH 0/3] drm/cma: use prim helpers instead GEM CMA specific dma_buf functionality

[Joonyoung Shim <jy0922.shim@xxxxxxxxxxx>]

Hi,

GEM CMA supports dma_buf but it needs GEM CMA specific functionality for
dma_buf. We can use prime helpers for dma_buf by commit
89177644a7b6306e6084a89eab7e290f4bfef397 "drm: add prime helpers", so
this patchset is to replace from using GEM CMA specific functions to
using prime helpers.

Thanks.

      drm/cma: add low-level hook functions to use prime helpers
      drm/cma: remove GEM CMA specific dma_buf functionality
