[PATCH 01/11] accel: ethosu: Fix ethosu_job_open() return value

[Rob Herring (Arm)]

A WARN_ON() returns a 0 or 1, not the original negative errno. Just drop
the WARN_ON() as the FD open will pass the return code to userspace and
there's only one possible source of the error (drm_sched_entity_init()).

Fixes: 5a5e9c0228e6 ("accel: Add Arm Ethos-U NPU driver")
