[Keyon] I don't want to fill "id" to kctl name, because sometimes it can be
string which can't be understood by PA, such as:
soc/intel/mfld_machine.c: ret_val = snd_soc_card_jack_new(runtime->card,
soc/intel/mfld_machine.c- "Intel(R) MID Audio Jack", SND_JACK_HEADSET |
soc/intel/mfld_machine.c- SND_JACK_BTN_0 | SND_JACK_BTN_1, &mfld_jack,
soc/omap/ams-delta.c: ret = snd_soc_card_jack_new(card, "hook_switch", SND_JACK_HEADSET,
soc/omap/ams-delta.c- &ams_delta_hook_switch, NULL, 0);

[Keyon] if PA can recognize "Front Headphone Jack" and "Rear Headphone Jack", then I
prefer to add a determine here:
if (!strcmp(id, "Front Headphone Jack") || !strcmp(id, "Rear Headphone Jack"))
create format("%s Jack", id) kctl;
