Subject: drm/amdgpu: Set vblank_disable_allowed = true
X-Git-Tag: v4.9.8~2296^2~1^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=354edd8e94e910a68bb74a434f055bc3600499f2;p=platform%2Fkernel%2Flinux-rpi3.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.
