Subject: drm/radeon: activate UVD clocks before sending the destroy msg
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=08ab0aac9ec2d6c07acb6bd96f3e9e872b3dfbaf;p=linux-edison.git

drm/radeon: activate UVD clocks before sending the destroy msg

commit c154a76311293f9671439286834aa325b7ef59fe upstream.

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