Subject: [PATCH 2/3] wl1251: fix bssid handling
Date: Thu, 26 Nov 2009 10:56:06 +0200 [thread overview]
Message-ID: <20091126085606.1564.29814.stgit@tikku> (raw)
In-Reply-To: <20091126085256.1564.77644.stgit@tikku>
From: Kalle Valo <kalle.valo@nokia.com>
bssid needs to be copied first in wl1251_op_bss_info_changed(), otherwise
templates will have incorrect bssid and power save will not work
correctly.
