Subject: [PATCH 3.12 124/142] drm/tilcdc: fix release order on exit

From: Guido Martínez <guido@...guardiasur.com.ar>

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

===============

commit eb565a2bbadc6a5030a6dbe58db1aa52453e7edf upstream.

Unregister resources in the correct order on tilcdc_drm_fini, which is
the reverse order they were registered during tilcdc_drm_init.

This also means unregistering the driver before releasing its resources.
