[PATCH 04/12] net-next: mediatek: invalid buffer lookup in mtk_tx_map()

From: John Crispin
Date: Thu May 05 2016 - 05:31:38 EST


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.
