From 0378b3f1c49d48ed524eabda7e4340163d9483c9 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 19 Jan 2009 11:20:52 -0500 Subject: cfg80211: add PM hooks This should help implement suspend/resume in mac80211, these hooks will be run before the device is suspended and after it resumes. Therefore, they can touch the hardware as much as they want to. Signed-off-by: Johannes Berg Signed-off-by: Bob Copeland Signed-off-by: John W.
