From 9ab12e88a0b46b4e6fa32bb0a2875c813a928e73 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 11 Sep 2017 00:08:01 +0200 Subject: drm/tve200: Clean up panel bridging This makes use of the drm_simple_display_pipe_attach_bridge() call and removes the two calls removing the bridge, which were erroneous: they unregister the bridge which is not what we want, we just want to unreference it and that is already handled by the core.
