[PATCH v2 0/5] drm/sched: Create wrapper to add a syncobj dependency to job

[Maíra Canal]

Some drivers perform the same operation to add a syncobj's fence to the sched
as a dependency: first, call drm_syncobj_find_fence() to find the fence and
then, call drm_sched_job_add_dependency(). Therefore, create a wrapper to
encapsulate those steps in one single function.

The first patch creates the wrapper for the operation and the following
patches make the drivers use the new function drm_sched_job_add_syncobj_dependency().

v1 -> v2: https://lore.kernel.org/dri-devel/20230208194817.199932-1-mcanal@igalia.com/T/

- Don't initialize any local return variables if it isn't necessary (Christian König).
- Remove unused "fence" variable from msm.
- Handle the -ENOENT case in v3d (Melissa Wen).
- Add Christian's, Alyssa's, and Luben's Reviewed-by.
