snd_soc_dapm_nc_pin_unlocked — permanently disable pin.
| int snd_soc_dapm_nc_pin_unlocked ( | struct snd_soc_dapm_context * dapm, | 
| const char * pin ); | 
   Marks the specified pin as being not connected, disabling it along
   any parent or child widgets.  At present this is identical to
   snd_soc_dapm_disable_pin but in future it will be extended to do
   additional things such as disabling controls which only affect
   paths through the pin.
   
Requires external locking.
