So now intel_uc_fini_hw should just take care of cleanup, hence s/intel_uc_fini_hw/intel_uc_cleanup. Correspondingly we also updated as s/i915_guc_submission_fini/i915_guc_submission_cleanup Other functionality to disable communication, disable interrupts and update of ggtt.invalidate is taken care by intel_uc_suspend. v2: Rebase w.r.t removal of GuC code restructuring. v3: Removed intel_guc_cleanup. (Michal Wajdeczko) v4: guc_free_load_err_log() needs to be called without checking i915.enable_guc_loading as this param is cleared on GuC load failure.
