From 11f6400e92aa3fc0aa936f20f7cc363674a4e3c4 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 29 Apr 2008 14:10:57 +0100 Subject: pata_via: Fix 6410 misdetect The discrete VIA ATA chips don't have 0x40 enable bits. We check that properly in one location but not another. This causes some users 6410 RAID cards to be incorrectly skipped.
