      This patch makes sure not to assign the_card if gaudio_open_snd_dev fails,
      since the parent function will deallocate the card.
      
      Also make sure all filp's in gaudio_open_snd_dev is assigned NULL upon error
      and gaudio_close_snd_dev only cleanups when the filp's are non-NULL.
