From: Gustavo Padovan Date: Mon, 1 Jun 2015 15:04:41 +0000 (-0300) Subject: drm/exynos: atomic phase 1: use drm_plane_helper_update() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=43dbdad2a9a6c64e3ce8339107d8666006ca2b5d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/exynos: atomic phase 1: use drm_plane_helper_update() Rip out the check from exynos_update_plane() and create exynos_check_plane() for the check phase enabling use to use the atomic helpers to call our check and update phases when updating planes. Update all users of exynos_update_plane() accordingly to call exynos_check_plane() before.
