From b8a3a5214d7cc115f1ca3a3967b7229d97c46f4a Mon Sep 17 00:00:00 2001 From: Auke Kok Date: Fri, 8 Jun 2007 15:46:30 -0700 Subject: PCI: read revision ID by default Currently there are 97 occurrences where drivers need the pci revision ID. We can do this once for all devices. Even the pci subsystem needs the revision several times for quirks. The extra u8 member pads out nicely in the pci_dev struct.
