[Openvortex-dev] Re : CVS: alsa-kernel/pci/au88x0 au88x0.c, 1.18, 1.19

[Raymond]

Refer to the recent change in CVS

http://cvs.sourceforge.net/viewcvs.py/alsa/alsa-kernel/pci/au88x0/au88x0.c?r1=1.18&r2=1.19

The au88x0 chips have known conflict with the following PCI devices

1) PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_8365_1
2) PCI_VENDOR_ID_VIA, PCI_EVICE_ID_VIA_82C598_1
3) PCI_VENDOR_ID_AMD, PCI_DEVICE_ID_AMD_FE_GATE_7007

The function of snd_vortex_workaround() is to detect the presence of
these devices and  perform vortex_fix_latency() and
vortex_fix_agp_bridge() automatically.

What is the difference between pci_find_device() and pci_get_device() ?

What is the purpose of adding pci_dev_put(via); at the end of
snd_vortex_workaround() ?
