Subject: drm/i915: Always call intel_update_sprite_watermarks() when disabling a plane
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a95fd8cae06dadf4a3eb88c9c130e86c5b0c1723;p=deliverable%2Flinux.git

drm/i915: Always call intel_update_sprite_watermarks() when disabling a plane

ILK and VLV codepaths didn't update sprite watermarks when disabling a
sprite. Make them do that.
