SubjectRe: [CFT] 3/6 (4): add SOCKET_CARDBUS_CONFIG flag
pcmcia-4.diff

Cardbus uses socket->cb_config to detect when the cardbus card has
been initialised. Since cb_config will eventually die, we need a
solution - introduce the SOCKET_CARDBUS_CONFIG flag, which is set
once we have initialised the cardbus socket.
