From 8cd812bcda06645160b0b279e1a125271a73411c Mon Sep 17 00:00:00 2001 From: "Winkler, Tomas" Date: Fri, 19 Dec 2008 10:37:43 +0800 Subject: [PATCH] iwl3945: use iwl_rb_status This patch makes use of iwl_rb_status also in 3945. The structure for 3945 is not the same but since only closed_rb_num filed is used in both cases there is no reason to duplicate it.
