From 8f88893c05f2f677f18f2ce5591b4bed5d4a7535 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 26 Sep 2011 17:38:50 +0200 Subject: PM: Update the policy on default wakeup settings This patch (as1485) documents a change to the kernel's default wakeup policy. Devices that forward wakeup requests between buses should be enabled for wakeup by default. Signed-off-by: Alan Stern Signed-off-by: Rafael J.
