Subject: drm/exynos: mixer: simplify mixer_graph_buffer()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1e60d62f3811e5c446738a85f61bed5d84de113b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/exynos: mixer: simplify mixer_graph_buffer()

DRM core already checks in drm_atomic_plane_check() if the
pixelformat is valid. Hence we can collapse the default case
of the switch statement with the XRGB8888 case.

No functional change.
