Subject: [PATCH V2 03/11] net: mediatek: invalid buffer lookup in mtk_tx_map()
Date: Fri, 10 Jun 2016 13:28:00 +0200	[thread overview]
Message-ID: <1465558088-15265-4-git-send-email-john@phrozen.org> (raw)
In-Reply-To: <1465558088-15265-1-git-send-email-john@phrozen.org>

The lookup of the tx_buffer in the error path inside mtk_tx_map() uses the
wrong descriptor pointer. This looks like a copy & paste error. Change the
code to use the correct pointer.
