Revision e8e5752dc0a56a01527055b0c37510b1d6b6b861 authored by Krzysztof Halasa on 17 December 2008, 08:24:13 UTC, committed by David S. Miller on 17 December 2008, 08:24:13 UTC
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); Signed-off-by: Krzysztof Halasa <khc@pm.waw.pl> Signed-off-by: David S.
