Subject: drm/amdgpu: Set vblank_disable_allowed = true
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=354edd8e94e910a68bb74a434f055bc3600499f2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/amdgpu: Set vblank_disable_allowed = true

Without this, since the conversion from drm_vblank_pre/post_modeset to
drm_vblank_on/off, the vblank interrupt could never be disabled after
userspace triggered enabling it.
