Subject: [PATCH 3/3] usb: qcserial add missing errorpath kfrees
Date: Mon, 04 Apr 2011 18:02:25 +0100 [thread overview]
Message-ID: <1301936545.4891.26.camel@shardy.csb> (raw)
In-Reply-To: <1301936257.4891.20.camel@shardy.csb>
There are two -ENODEV error paths in qcprobe where the allocated private
data is not freed, this patch adds the two missing kfrees to avoid
leaking memory on the error path
