Subject: [PATCH 3.13 064/187] drm/tilcdc: tfp410: fix dangling sysfs connector node

3.13.11.7 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?Guido=20Mart=C3=ADnez?= <guido@...guardiasur.com.ar>

commit 16dcbdef404f4e87dab985494381939fe0a2d456 upstream.

Add a drm_sysfs_connector_remove call when we destroy the panel to make
sure the connector node in sysfs gets deleted.

This is required for proper unload and re-load of this driver, otherwise
we will get a warning about a duplicate filename in sysfs.
