PCI: PCIe portdrv: Simplify suspend and resume
Simplify suspend and resume of the PCI Express port driver. It no longer needs to save and restore the standard configuration space of the device; this is now done by the PCI PM core layer. This patch is reported to fix the regression tracked as http://bugzilla.kernel.org/show_bug.cgi?id=12598 Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Reported-and-tested-by: Parag Warudkar <parag.lkml@gmail.com> Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
