The reclaim_buffers function of the savage driver actually wants to run with the hw_lock held - at least there are printks in the call-chain to that effect. But the drm core only calls reclaim_buffers as used by savage _after_ forcefully dropping the hwlock (in case it's still hold by the closing fd). So do the same idlelock dance as for the other dma drivers and hope that papers over any issues. v2: Don't let the idlelock linger around.
