From 4147200d25c423e627ab4487530b3d9f2ef829c8 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 25 Jun 2010 14:02:14 -0400 Subject: USB: add do_wakeup parameter for PCI HCD suspend This patch (as1385) adds a "do_wakeup" parameter to the pci_suspend method used by PCI-based host controller drivers. ehci-hcd in particular needs to know whether or not to enable wakeup when suspending a controller. Although that information is currently available through device_may_wakeup(), when support is added for runtime suspend this will no longer be true.
