      ALSA: sound/pci/mixart/mixart.c: Add missing snd_card_free · 73f6a12e
      由 Julia Lawall 提交于 
      The function snd_mixart_create creates a link between mgr and card that
allows snd_mixart_free to free card as well.  But if snd_mixart_create
fails, then the link has not been created and card has to be freed explicitly.

The semantic match that finds the problem is as follows:
