Originally drm_sched_job_init was the point of no return, after which drivers really should submit a job. I've split that up, which allows us to fix this issue pretty easily. Only thing we have to take care of is to not skip to error paths after that. Other drivers do this the same for out-fence and similar things. v2: It's not really a bugfix, just an improvement, since all drm_sched_job_arm does is reserve the fence number. And gaps should be fine, as long as the drm_sched_job doesn't escape anywhere at all. For robustness it's still better to align with other drivers here and not bail out after job_arm(). v3: I misplaced drm_sched_job_arm by _one_ line! Thanks to Rob for testing and debug help.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
