ahci/pata_jmicron: match class not function number
Browse files Browse the repository at this point in the history 
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.
