net: kernel BUG at drivers/net/phy/mdio_bus.c:165!
kernel BUG at drivers/net/phy/mdio_bus.c:165!
Unable to handle kernel NULL pointer dereference at virtual address 00000000
How?
mdiobus_alloc() sets bus->state = MDIOBUS_ALLOCATED.
mdiobus_register() sets bus->state = MDIOBUS_REGISTERED but then can
fail (mdiobus_scan()) returning an error to the caller.
The caller aborts correctly with mdiobus_free() which does:
if (bus->state == MDIOBUS_ALLOCATED) {
kfree(bus);
return;
}
BUG_ON(bus->state != MDIOBUS_UNREGISTERED);
