From 0836e6d8c47416d6eb60bb68a5d7213c0c2d0d29 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 10 Sep 2015 18:59:08 +0300 Subject: [PATCH] drm/i915: Move sprite/cursor plane disable to intel_sanitize_crtc() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Move the sprite/cursor plane disabling to occur in intel_sanitize_crtc() where it belongs instead of doing it in intel_modeset_readout_hw_state(). The plane disabling was first added in 4cf0ebbd4fafbdf8e6431dbb315e5511c3efdc3b drm/i915: Rework plane readout. I got the idea from some patches from Partik and/or Maarten but those moved also the plane state readout to intel_sanitize_crtc() which isn't quite right in my opinion.
