That means a functional change in one place (alc882_quirks.c), where 
there are line_out_pins but automute for line out is not set:

@@ -2568,8 +2554,7 @@ static void alc888_lenovo_ms7195_setup(struct 
hda_codec *codec)
         spec->autocfg.hp_pins[0] = 0x1b;
         spec->autocfg.line_out_pins[0] = 0x14;
         spec->autocfg.speaker_pins[0] = 0x15;
-       spec->automute = 1;
-       spec->automute_mode = ALC_AUTOMUTE_AMP;
+       alc_simple_setup_automute(spec, ALC_AUTOMUTE_AMP, 1, 0, 0, 1);
  }

If you don't mind that change I can do what you suggest.
