Use localized __diag_push(), __diag_ignore_all() with rationale, and
__diag_pop() for specific initializations instead of blanket disabling
of -Woverride-init across several files.

Check return value for drmm_mutex_init as it can fail and return on
failure.

Enable only one CCS engine by default with all the compute sices
allocated to it.
While generating the list of UABI engines to be exposed to the
user, exclude any additional CCS engines beyond the first
instance.
This change can be tested with igt i915_query.
Fixes: d2eae8e98d59 ("drm/i915/dg2:
We want a fixed load CCS balancing consisting in all slices
sharing one single user engine. For this reason do not create the
intel_engine_cs structure with its dedicated command streamer for
CCS slices beyond the first.
Fixes: d2eae8e98d59 ("drm/i915/dg2: Drop force_probe requirement")
The hardware should not dynamically balance the load between CCS
engines. Wa_14019159160 recommends disabling it across all
platforms.

Hi,
I think we are at the end of it and hopefully this is the last
version. Thanks Matt for having followed this series until here.
This series does basically two things:
1. Disables automatic load balancing as adviced by the hardware
workaround.
2. Assigns all the CCS slices to one single

I thought I had cleaned up the 'gem/' directory in the past, but
still, old aficionados of the 'dev_priv' name keep sneaking it
in.
