If you do export the function, please make its comments prettier, so
that it appears in kernel documentation properly as an API function.
Also, in general, we use snd_ prefix for the exported stuff.
You'd need to rename it accordingly, too.
Last but not least, this is specific to ASoC, so use "ASoC" prefix to
the subject line.
thanks,
