Subject: [PATCH 20/29] net: mv643xx_eth: use phy_disconnect instead of
|
|
phy_detach
|
|
|
|
Using a separated mdio bus driver with mvmdio, phy_detach on network device
|
|
removal will not stop the phy and finally lead to NULL pointer dereference
|
|
in mvmdio due to non-existent network device. Use phy_disconnect instead
|
|
to properly stop phy device from accessing network device prior removal of
|
|
the network device.
