Uh apologies for missing this again, the entire point of v2 was to fix this across all drivers. But somehow the fixup for etnaviv got lost. I'll do it now for v3.

To clarify, in case you meant I should put it into submit_cleanup(): That doesn't work, because for some of the paths we shouldn't call it yet, so I think it's better to be explicit here (like I've done with other drivers) - drm_sched_job_cleanup handles being called before/after drm_sched_job_arm, but it doesn't cope well with being called before drm_sched_job_init :-) -Daniel > > Thanks, Daniel > > > > > Regards, > > Lucas > > > > > ret = submit_lookup_objects(submit, file, bos, args->nr_bos);
