You're right. I removed 'max98927_reg_get' and 'max98927_reg_put' function to avoid duplication. > > <snip> >> +static int max98927_boost_voltage_get(struct snd_kcontrol *kcontrol, >> + struct snd_ctl_elem_value *ucontrol) { >> + return max98927_reg_get(kcontrol, ucontrol, >> + MAX98927_R0040_BOOST_CTRL0, >> + MAX98927_BOOST_CTRL0_VOUT_MASK, 0); } >> + > > And can't these just be specified in the normal way with the register information attached to the control? There doesn't seem to be any special behaviour being added here. Apologies if I am missing something here. Thank you for your feedback. Now SOC_ENUM_EXT was replaced by SOC_ENUM. SOC_SINGLE_EXT was also replaced by SOC_SINGLE. Above function is no longer being used. > > Thanks, > Charles _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
