From 85b8582d7ca516030efb84d94fa29a73c1d9a125 Mon Sep 17 00:00:00 2001 From: Vincent Palatin Date: Mon, 5 Dec 2011 11:51:18 -0800 Subject: 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.
