Subject: [PATCH 084/102] net-next: mediatek: invalid buffer lookup in
|
|
|
|
|
mtk_tx_map()
|
|
|
|
|
|
|
|
|
|
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.
