the functions:
	snd_ice1712_akm4xxx_build_controls
	snd_ice1712_build_pro_mixer
	snd_ctl_add
	snd_ak4114_build
	prodigy192_ak4114_init
	snd_ak4113_build
are all returning either 0 or a negetive error value.
so we can easily remove the check for a negative value and return
the value instead.

i have not given Jaroslav Kysela <perex@perex.cz> in the To list,
as in my last mail, all mails bounced with the error:
"cant create user output file"

In doing so, you can rewrite to return directly like
	return xxx();
instead of
	err = xxx();
	return err;
