Subject: drm/i915: Don't try to enable cursor from setplane when crtc is disabled
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1add143caf593cfc7514f1c83470fba0664ae0a3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Don't try to enable cursor from setplane when crtc is disabled

Make sure the cursor gets fully clipped when enabling it on a disabled
crtc via setplane. This will prevent the lower level code from
attempting to enable the cursor in hardware.
