From: Gustavo Padovan gustavo.padovan@collabora.co.uk
struct exynos_drm_overlay has no practical advantage nor serves as important piece of the exynos API design. The only place it was used was inside the struct exynos_plane which was just causing a extra access overhead. Users had to access the overlay first and just then get the plane information it contains.
This patch merges struct exynos_drm_overlay into struct exynos_plane. It also renames struct exynos_plane to struct exynos_drm_plane.
The rational is to cut one step to access plane information.
