+out_azx_free:

•                 azx_free(chip);
  

This is superfluous. Once when azx_create() succeeds, azx_free() is called from snd_card_free(). That is...

•                 pci_set_drvdata(pci, NULL);
  

... only this call was missing. And this can be put under out_free label, as this is safe to call at any exit path. So, it'll be a oneliner patch.

thanks,

Takashi
