From ac17a947a4f47b642097d6814d6dcc60c297eb17 Mon Sep 17 00:00:00 2001 From: Tomas Winkler Date: Thu, 25 Oct 2007 17:15:37 +0800 Subject: iwlwifi: replacing wording restricted to nic access in iwl-io This patch replaces wording 'restricted' with more appropriate 'nic access' NIC access is grabbed to prevent NIC entering power save mode General cleanup of iwl-io.h Signed-off-by: Tomas Winkler Signed-off-by: John W.
