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; };

The driver field holds the minimal ID string of the chip. This is used by alsa-lib's configurator, so keep it simple but unique. Even the
