ahci/pata_jmicron: match class not function number
Make jmiron_ata quirk update pdev->class after programming the device and update ahci and pata_jmicron such that they match class code instead of checking function number manually. For ahci, it matches for vendor and class. For pata_jmicron, it matches vendor, device and class as IDE class isn't as well defined as AHCI class. This makes jmicron device matching more conventional and script friendly. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
