[PATCH] pcmcia: au1000_generic fix
The previous code did something like,
if (error) goto out_err;
....
do {
struct au1000_pcmcia_socket *skt = PCMCIA_SOCKET(i);
del_timer_sync(&skt->poll_timer);
pcmcia_unregister_socket(&skt->socket);
out_err:
flush_scheduled_work();
ops->hw_shutdown(skt);
i--;
} while (i > 0)
.....
- On the error path, skt would not contain a valid value for the first
iteration (skt is masked by uninitialized automatic skt)
- Does not do hw_shutdown() for 0th element of PCMCIA_SOCKET
