[alsa-devel] [PATCH] ALSA: hda/ca0132 - make pci_iounmap() call conditional
When building without CONFIG_PCI, we can (depending on the architecture) get a link failure:
ERROR: "pci_iounmap" [sound/pci/hda/snd-hda-codec-ca0132.ko] undefined!
Adding a compile-time check for PCI gets it to work correctly on 32-bit ARM.

The proper "fix" would be to make this working for SH no matter which config is... But pci_iomap and pci_iounmap() are such a mess, and no one really cares about SH nowadays, so I'd take this easier way.
thanks,
Takashi
