it's a real compilation bug (not a mistake of your toolchain). The
init_module function is defined both in qlogic_stub.c and in qlogicfas.c
that imports scsi_module.c. One of the two has to go away or it can't
link due a name clash across two objects.

after a first look I'm unsure what's the right fix. I guess the init
module of the _cs has to get priority over the scsi_module.c. so
basically you could hack something to disable the include of
scsi_module.c from the other file. This assumes the _cs init_module will
eventually register the scsi device too from the pcmcia callback.

However this should be a generic problem not introduced by my changes.
Is there any scsi or pcmcia person interested in fixing it?
