Subject: [PATCH] iris: Fix return of xe_batch_submit() when exec fails
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When intel_ioctl(DRM_IOCTL_XE_EXEC) fails it returns -1 sets errno
with the fail reason.
This fail reason is than is used to know if engine was banned in
context_or_engine_was_banned().

Not adding a fixes tag because Xe is not enabled by default.
