Subject: drm/tegra: dc: No longer disable planes at CRTC disable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=50a246aa13b80c8310dc5a82be639a60868f667e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/tegra: dc: No longer disable planes at CRTC disable

The DRM core should take care of disabling all unneeded planes, so there
is no need to do this explicitly.
