Subject: [net PATCH] net: dsa: qca8k: fix NULL pointer dereference for
|
|
of_device_get_match_data
|
|
|
|
of_device_get_match_data is called on priv->dev before priv->dev is
|
|
actually set. Move of_device_get_match_data after priv->dev is correctly
|
|
set to fix this kernel panic.
|
|
|
|
Fixes: 3bb0844e7bcd ("net: dsa: qca8k: cache match data to speed up access")
