Hi,
snd_soc_dapm_put_enum_double( ) returns 0 to indicate success;
otherwise an error number. The value in the function is retrieved
from dapm_kcontrol_set_value( ).

However, dapm_kcontrol_set_value( ) returns a boolean.

If the value has updated successfully, dapm_kcontrol_set_value( ) will
return 1 and snd_soc_dapm_put_enum_double( ) will also return 1. The
value is inverted.
