Nothing special going on here.
Aside reviewing the code, it seems like drm_sched_job_arm() should be
moved into lima_sched_context_queue_task and put under some mutex
together with drm_sched_push_job(). See the kerneldoc for
drm_sched_push_job().
v2: Rebase over renamed functions to add dependencies.
