From: Pavel Machek Date: Sun, 17 Sep 2006 17:39:06 +0000 (+0200) Subject: set power state of firewire host during suspend X-Git-Tag: v2.6.19-rc1~644^2~5 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f0645e7720e0baacbde61d7d1f0180309451c695;p=linux-2.6 set power state of firewire host during suspend Put firewire host controller in PCI Dx state for system suspend. (I was not able to measure any power savings, but it sounds like right thing to do, anyway.) Signed-off-by: Pavel Machek Update by stefanr: Shuffle with existing PPC_PMAC code. Set power state in the resume hook too.
