Subject: [PATCH] net: ethernet: mtk_eth_soc: fix NULL pointer dereference
|
|
|
|
Check for NULL pointer to avoid kernel crashing in case of missing WO
|
|
firmware in case only a single WEDv2 device has been initialized, e.g. on
|
|
MT7981 which can connect just one wireless frontend.
|
|
|
|
Fixes: 86ce0d09e424 ("net: ethernet: mtk_eth_soc: use WO firmware for MT7981")
