 /**
  *  snd_card_register - register the soundcard
  *  @card: soundcard structure
  *
  *  This function registers all the devices assigned to the soundcard.
  *  Until calling this, the ALSA control interface is blocked from the
  *  external accesses.  Thus, you should call this function at the end
  *  of the initialization of the card.
  *
  *  Returns zero otherwise a negative error code if the registrain failed.
