Subject: [PATCH 3.11 140/272] drm/radeon: activate UVD clocks before sending the destroy msg

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

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

From: =?UTF-8?q?Christian=20K=C3=B6nig?= <christian.koenig@....com>

commit c154a76311293f9671439286834aa325b7ef59fe upstream.

Make sure the UVD clocks are still active before sending
the destroy message, otherwise the hw might hang.
