From de115fac7388264f6f1865a12ea6e4101bd05c48 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 5 Mar 2015 19:41:04 +0200 Subject: [PATCH] drm: rcar-du: Fix framebuffer reference leak through plane state Plane state duplication takes a reference to the framebuffer stored in the state, but state destroy doesn't release it. This causes a reference leak. Fix it.
