Subject: [PATCH 2/4] mwifiex: remove unreachable code
Date: Mon, 26 Sep 2011 20:37:24 -0700	[thread overview]
Message-ID: <1317094646-7718-2-git-send-email-bzhao@marvell.com> (raw)
In-Reply-To: <1317094646-7718-1-git-send-email-bzhao@marvell.com>

From: Amitkumar Karwar <akarwar@marvell.com>

In disconnected state "iw dev mlan0 link" command will return
from cfg80211 stack itself. We also have an error check in
mwifiex_cfg80211_get_station() routine. Therefore the code
under "if (!priv->media_connected)" condition in
mwifiex_rate_ioctl_get_rate_value() routine becomes unreachable.
