From 7b993855dfd5d87e07ac84285d3d9bb0c743dede Mon Sep 17 00:00:00 2001 From: Daniel Schultz Date: Fri, 23 Sep 2016 12:52:49 +0200 Subject: [PATCH] drm/tilcdc: fix wrong error handling When 'component_bind_all' fails it should not try to unbind components in the error handling. This will produce a null pointer kernel panic when no component exist. This patch changes the order of the error handling. Now, it will only unbind components if the are bound. Otherwise, the module will jump to an error label below.
