Steven Price 5a90861ed6 drm: Don't free jobs in wait_event_interruptible() ... [ Upstream commit 588b9828f0 ] drm_sched_cleanup_jobs() attempts to free finished jobs, however because it is called as the condition of wait_event_interruptible() it must not sleep. Unfortunately some free callbacks (notably for Panfrost) do sleep. Instead let's rename drm_sched_cleanup_jobs() to drm_sched_get_cleanup_job() and simply return a job for processing if there is one. The caller can then call the free_job() callback outside the wait_event_interruptible() where sleeping is possible before re-checking and returning to sleep if necessary.
