I guess it's a part of series, right?
If so, feel free to take my ack for this patch.

  Acked-by: Takashi Iwai <tiwai@...e.de>

BTW, we should use EXPORT_SYMBOL_GPL() for new entries in general.
OTOH, it won't match with others in the same file, and it may look
inconsistent.  So, I don't mind either way.


thanks,

Takashi
