instead have a call down from the PCMCIA mid-layer to set it. Use this from pcmcia_function_enable(). (Currently the policy is the same, but this would allow for more flexibility in deciding which mode to use.) Now it is safe to hold the socket enabled during attach, so do that. Only one enable/disable cycle to attach a card now!
