X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0d014ff344abc9c8e56cf1870ab3a144d2e2e37a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Remove double wait_for_vblank on broadwell. wait_vblank is already set in intel_plane_atomic_calc_changes for broadwell, waiting for a double vblank is overkill.
