From b47ef2438dea2ddad4561152aa8007a2d95e8157 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Mon, 17 Dec 2007 13:26:42 -0500 Subject: [PATCH] libertas: handle HOST_AWAKE event by sending WAKEUP_CONFIRM command lbs_send_confirmwake() is a bit ugly but matches the way we confirm sleep. We'll deal with that whole thing later. Signed-off-by: David Woodhouse Signed-off-by: John W.
