Remove the three remaining pcmcia_get_configuration_info() users:
- pcmciamtd is marked broken anyway.
- serial_cs.c can access the relevant structs directly
- ipwireless didn't use the output

[PATCH 31/39] pcmcia: deprecate CS_NO_MORE_ITEMS

[Dominik Brodowski]

CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if
the end of a tuple chain is reached. As at least one PCMCIA driver relies
on matching this return value, replace it with -ENOSPC which is now
uniquely used for this purpose within the in-kernel pcmcia subsystem.

Re: [PATCH 14/39] pcmcia: use pcmcia_loop_config in misc pcmcia drivers

[Harald Welte]

Thanks for your patch, Dominik,

On Mon, Aug 18, 2008 at 08:53:05PM +0200, Dominik Brodowski wrote:

> Use the config loop helper in misc pcmcia drivers.

This looks fine to me (for cm4000_cs and cm4040_cs), although I cannot test it
since I'm currently travelling for more than a month and don't have the device
with me.

Can you (or anyone else who has the hardware) give it a short test if it
actually still enumerates the hardware correctly?

Thanks.
