It's no longer called from this place as of:
commit 7762ebb9a455db18eef5c366da5496fb38429d56
Author: Sagar Arun Kamble <sagar.a.kamble@xxxxxxxxx>
drm/i915/guc: Release GuC interrupts in i915_guc_submission_disable
Also, I did similar thing in my GuC series (for guc_loader.c only). It
should be easy to rebase one on top of the other depending which will
get there first.
Othere changes here LGTM
