Subject: [PATCH 11/14] drm/i915: Don't leak primary/cursor planes on crtc init failure
Date: Tue,  8 Dec 2015 18:41:59 +0200	[thread overview]
Message-ID: <1449592922-5545-12-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1449592922-5545-1-git-send-email-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Call intel_plane_destroy() instead of drm_plane_cleanup() so that we
also free the plane struct itself when bailing out of the crtc init.

And make intel_plane_destroy() NULL tolerant to avoid having to check
for it in the caller.
