maybe instead of doing 3x same deref, just add at the start:

	struct intel_guc *guc = &engine->gt->uc.guc;

maybe we can avoid i915/gt dance with:

	struct intel_guc *guc = huc_to_uc(huc)->guc;

maybe first add:

	struct intel_uc *uc = &i915->gt.uc;
then
	struct intel_uc_fw *guc_fw = &uc->guc.fw;
	struct intel_uc_fw *huc_fw = &uc->huc.fw;
