From e123b4edb2a13b67c4de7caee2e3d5e083bef58b Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Wed, 4 May 2022 11:02:29 +0200 Subject: drm/etnaviv: avoid cleaning up sched_job when submit succeeded While the labels may mislead the casual reader, the tail of the function etnaviv_ioctl_gem_submit is always executed, as a lot of the structures set up in this function need to be cleaned up regardless of whether the submit succeeded or failed. An exception is the newly added drm_sched_job_cleanup, which must only be called when the submit failed before handing the job to the scheduler.
