Subject: drm/atomic: add all affected planes in drm_atomic_helper_check_modeset
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=57744aa7cfb5969c5a0621f4cfa45bb83d391064;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

drm/atomic: add all affected planes in drm_atomic_helper_check_modeset

Drivers may need to recalculate plane state when a modeset occurs,
not reliably adding them might cause hard to debug bugs.
