Subject: [PATCH] airo: return from set_wep_key() when key length is zero
Date: Tue, 9 Feb 2010 09:27:19 +0100 [thread overview]
Message-ID: <20100209082718.GA2588@dhcp-lab-161.englab.brq.redhat.com> (raw)
In-Reply-To: <20100208205358.GA3852@tuxdriver.com>
Even if keylen == 0 is a bug and should not really happen, better avoid
possibility of passing bad value to firmware.
