ALSA: doc: my_chip has no element ioport
chip->ioport is dereferenced in two places, but the struct is defined as follows: struct mychip { struct snd_card *card; struct pci_dev *pci; unsigned long port; int irq; }; Signed-off-by: Christina Quast <cquast@hanoverdisplays.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
