From 06e03f8ce91b71c6ce4134c8bf9ed801aed0382c Mon Sep 17 00:00:00 2001 From: Don Fry Date: Tue, 7 Feb 2012 14:21:32 -0800 Subject: [PATCH] iwlwifi: changes args to iwl_nic for firmware operations Remove the references to iwl_priv from the firmware request and parsing routines. They are generic to the nic.
