some PCMCIA SCSI drivers can be built *only* as modules

[Robert P. J. Day]

drivers/scsi/pcmcia/Kconfig:
...
config PCMCIA_AHA152X
        tristate "Adaptec AHA152X PCMCIA support"
        depends on m && !64BIT
        select SCSI_SPI_ATTRS
        help
          Say Y here if you intend to attach this type of PCMCIA SCSI host
          adapter to your computer.

          To compile this driver as a module, choose M here: the
          module will be called aha152x_cs.
...

  it would seem to make no sense that the "depends on" clause for this
option includes "m", forcing this (and all other four entries in that
Kconfig file, by the way) to be built as modules, while the help text
for all five entries suggests you can select "y".

  as jack nicholson would say, something's gotta give.

LSML a.k.a. linux-scsi may know what's gotta give.

In the old days pcmcia drivers had to be modular because pcmcia required
a lot of userspace setup.  It's not needed anymore these days and the
dependencies can go.

I agree the non-legacy (CardBus and beyond) ones can be built in.  I
thought the legacy 8 and 16 bit type I and II still had to be modular
because they still need setting up.

nope.  While I don't have a pcmcia scsi card my 16 bit pcmcia wireless
cards work perfectly fine without any previous setup.

OK ... I had the opposite experience ... A ZoomAir 802.11b card wasn't
working because I'd accidentally config'd it non-modular.  However, if
Dominik confirms it's all supposed to work non-modular, I'm happy to
conclude my experience was pilot error.

PCMCIA card drivers should (famous last words) work just fine if built as
modules. They may not be bound to devices, depending on the arch and 
system, until userspace tools have run, but this is independent of modular
or built-in drivers. So a full ACK on this.

Thanks,
