Subject: [PATCH v3 09/20] drm/i915: Fill in more crtc state, v3.
Date: Mon, 13 Jul 2015 16:30:22 +0200	[thread overview]
Message-ID: <1436797833-11493-10-git-send-email-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <1436797833-11493-1-git-send-email-maarten.lankhorst@linux.intel.com>

There is a small memory leak in intel_modeset_readout_hw_state,
plug it.

intel_sanitize_crtc should set a null mode when disabling the crtc,
this updates crtc_state->enable too.

intel_sanitize_crtc also needs to update the vblank timestamps before
enabling vblank to make it work right.

Changes since v1:
- Moved after reworking primary plane and updating mode members.
- Force a modeset calculation by changing mode->type from what the
  final mode will be.
Changes since v2:
- Do not fill out mode, this should only be done for supporting fastboot.
