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

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.
