[PATCH 11/18] pcmcia: do not use io_req_t when calling pcmcia_request_io()

[Komuro]

Hi,

With this patch, fmvj18x_cs based card works (both network and serial).

but Serial part of Xircom card still does not work.

I think the reason is irq or io_width or io_lines is not setuped properly
for Xircom-card by pcmcia_core.
