[PATCH v2 2/3] drm/i915/error: standardize function style in error capture

[Daniele Ceraolo Spurio]

some of the static functions used from capture() have the "i915_"
prefix while other don't; most of them take i915 as a parameter, but one
of them derives it internally from error->i915. Let's be consistent by
avoiding prefix for static functions and by getting i915 from
error->i915. While at it, s/dev_priv/i915 in functions that don't
perform register reads.

v2: take i915 from error->i915 (Michal), s/dev_priv/i915,
    update commit message

[PATCH v2 3/3] drm/i915/error: capture uc_state after gen_state

[Daniele Ceraolo Spurio]

error->device_info.has_guc, which we check in capture_uc_state, is set
in capture_gen_state, so the latter needs to be performed first.

v2: rebased

Following the fist part of this logic, i915_error_object_free could 
probably be just error_object_free, but this would never end...

Changes look OK to me, feel free to add my r-b if you need it.

also, it looks that we are not consistent in using capture vs. record  
verb...
but cleanup of all above nitpicks can be continued in another spin, so
