snd_soc_kcontrol_codec — Returns the CODEC that registered the control
struct snd_soc_codec * snd_soc_kcontrol_codec ( | struct snd_kcontrol * kcontrol); |
This function will only work correctly if the control has been
registered with snd_soc_add_codec_controls or via table based setup of
snd_soc_codec_driver. Otherwise the behavior is undefined.
