net: Add missing TST_CFG_WRITE bits around sky2_pci_write
Add missing TST_CFG_WRITE bits around sky2_pci_write*() in Optima setup routines. Without the cfg-write bits, the driver may spew endless link-up messages through qlink irq. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
