Subject: [PATCH v5 8/8] drm/i915: Remove vblank wait from hsw_enable_ips, v2.
Date: Wed, 23 Mar 2016 14:33:28 +0100	[thread overview]
Message-ID: <56F29B28.5070804@linux.intel.com> (raw)
In-Reply-To: <1455278797.2594.60.camel@intel.com>

intel_post_plane_update did an extra vblank wait that's no longer needed when enabling ips.

Changes since v1:
- Add comment explaining why vblank wait is performed. (Paulo)

Noticed this one still in my branch, does this look ok?
