Subject: [PATCH 43/43] iwl3945: use iwl_rb_status
Date: Fri, 19 Dec 2008 10:37:43 +0800 [thread overview]
Message-ID: <1229654263-21454-44-git-send-email-yi.zhu@intel.com> (raw)
In-Reply-To: <1229654263-21454-43-git-send-email-yi.zhu@intel.com>
From: Winkler, Tomas <tomas.winkler@intel.com>
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.
