From f60dc0138aa19769bf8bab9f93b043235428b66f Mon Sep 17 00:00:00 2001 From: "John W. Linville" Date: Mon, 25 Oct 2010 16:12:37 -0400 Subject: [PATCH] iwlwifi: Convert to new PCI PM framework Use the new PCI PM and let the PCI core code handle the PCI-specific details of power transitions. Based on similarly titled ath9k patch posted by Rafael J. Wysocki. Signed-off-by: John W. Linville Acked-by: Rafael J.
