Merge branch 'drm-fixes-3.14' of git://people.freedesktop.org/~agd5f/linux into drm-fixes
A few more radeon fixes. * 'drm-fixes-3.14' of git://people.freedesktop.org/~agd5f/linux: drm/radeon/cik: properly set compute ring status on disable drm/radeon/cik: stop the sdma engines in the enable() function drm/radeon/cik: properly set sdma ring status on disable drm/radeon: fix runpm disabling on non-PX harder
