Huh? Platform has been in the kernel for ages. At least since 2.6.9,
probably since 2.6.0.

I've found a machine to fiddle with. I has a floppy controller, but no
floppy drive. But when I removed 'parent == NULL' from your hack I at
least got:

16124: 22:57:42.943: probe-pc-floppy.c:73: Checking if /dev/fd0 is
actually present
16124: 22:57:42.945: probe-pc-floppy.c:88: floppy drive name is 'H1440'
16124: 22:57:43.633: probe-pc-floppy.c:96: floppy drive /dev/fd0 seems
not to exist

It would seem some hacking is till needed since the platform information
cannot provide any decent information about the actual device. Perhaps
we could scan all block devices with the ioctl:s in probe-pc-floppy and
use that?


I have to run off now, but if you have some ideas on how to proceed I
can continue this tomorrow.
