3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christian König <christian.koenig@xxxxxxx>
commit c154a76311293f9671439286834aa325b7ef59fe upstream.
Make sure the UVD clocks are still active before sending
the destroy message, otherwise the hw might hang.
