From ad8cfa1defee14a5181d9b63e666318c51cfaeed Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 7 Jan 2009 13:09:37 +0100 Subject: [PATCH] PCI PM: Call pci_fixup_device from legacy routines The size of drivers/pci/pci-driver.c can be reduced quite a bit if pci_fixup_device() is called from the legacy PM callbacks, so make it happen. No functional changes should result from this. Signed-off-by: Rafael J.
