[PATCH 8/9] drm/i915: Don't leak primary/cursor planes on crtc init failure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

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.
