Subject: [PATCH 109/250] net: ethernet: mtk_eth_soc: fix NULL pointer on hw
|
|
reset
|
|
|
|
When a hardware reset is triggered on devices not initializing WED the
|
|
calls to mtk_wed_fe_reset and mtk_wed_fe_reset_complete dereference a
|
|
pointer on uninitialized stack memory.
|
|
Break out of both functions in case a hw_list entry is 0.
|
|
|
|
Fixes: 08a764a7c51b ("net: ethernet: mtk_wed: add reset/reset_complete callbacks")
