cover drm/exynos: cleanup and update gem/dma-buf
This patchset improves gem and dma-buf codes of exynos drm.
Major changes:
- remove needless using sg table.
- use prime helpers instead of exynos specific dma-buf functions.
- merge struct exynos_drm_gem_buf in struct exynos_drm_gem.
- remove simple functions.
- cleanup.
Thanks.
