Merge branch 'drm-fixes-4.1' of git://people.freedesktop.org/~agd5f/linux into drm-fixes
Mostly stability fixes for UVD and VCE, plus a few other bug and regression fixes. * 'drm-fixes-4.1' of git://people.freedesktop.org/~agd5f/linux: drm/radeon: stop trying to suspend UVD sessions drm/radeon: more strictly validate the UVD codec drm/radeon: make UVD handle checking more strict drm/radeon: make VCE handle check more strict drm/radeon: fix userptr lockup drm/radeon: fix userptr BO unpin bug v3 drm/radeon: don't setup audio on asics that don't support it drm/radeon: disable semaphores for UVD V1 (v2)
