From e34bb370dec4919b7e8b769d51ad2bc2535b6982 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 26 Feb 2007 20:24:03 +0900 Subject: 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.
