PCI/PM/Runtime: make PCI traces quieter
When the runtime PM is activated on PCI, if a device switches state frequently (e.g. an EHCI controller with autosuspending USB devices connected) the PCI configuration traces might be very verbose in the kernel log. Let's guard those traces with DEBUG condition. Acked-by: "Rafael J. Wysocki" <rjw@sisk.pl> Signed-off-by: Vincent Palatin <vpalatin@chromium.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
