From 3d69215c59b4f34732ed0baa0c4bc91ce8f85409 Mon Sep 17 00:00:00 2001 From: "John W. Linville" Date: Wed, 15 Feb 2012 16:37:52 -0500 Subject: [PATCH] compat-wireless: remove olpc_ec_wakeup_* calls for pre-3.1 kernels This section of the libertas driver calls functions that simply don't exist before the release of 3.1. This code in question was an addition, not a change from any existing code. It is safe to simply remove it for older kernels. Signed-off-by: John W. Linville Signed-off-by: Luis R.
