net/ethernet: ks8851_mll fix irq handling
There a two different irq variables ks->irq and netdev->irq. Only ks->irq is set on probe, so disabling irq in ks_start_xmit fails. This patches remove ks->irq from private data and use only netdev->irq. Tested on a kernel 3.0 based OMAP4430 SMP Board Signed-off-by: Jan Weitzel <j.weitzel@phytec.de> Signed-off-by: David S. Miller <davem@davemloft.net>
