From ea30759643b423933ced48acdd78e5299f05295b Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Fri, 8 Jun 2007 15:14:31 +0200 Subject: [PATCH] ide: generic IDE PCI driver, add another device exception generic IDE PCI driver, add another device exception This device is char device and is grabbed by generic ide driver: 00:0b.0 Class ffff: National Semiconductor Corporation 87410 IDE (rev ff) (prog-if ff) Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Disallow generic IDE PCI driver to grab it by adding next condition. Also consolidate exceptions to one bigger 'switch (dev->vendor)'.
