Geert Uytterhoeven e5779a583d scsi/m68k: Kill NCR_700_detect() warnings
The patch from Ming Lei <tom.leiming@gmail.com> entitled:
    platform driver: fix incorrect use of 'platform_bus_type' with 'struct devic
introduced the following warnings on m68k, as `dev' is now a `struct
platform_device *' instead of a `struct device *':

| drivers/scsi/a4000t.c:64: warning: passing argument 3 of 'NCR_700_detect' from incompatible pointer type
| drivers/scsi/mvme16x_scsi.c:67: warning: passing argument 3 of 'NCR_700_detect' from incompatible pointer type
| drivers/scsi/bvme6000_scsi.c:61: warning: passing argument 3 of 'NCR_700_detect' from incompatible pointer type

I think the below is missing (untested on real hardware).
