[PATCH] 2.4.17-pre7: fdomain_16x0_release undeclared

[Pavel Roskin]

Hello, Alan and all!

File drivers/scsi/fdomain.h declares a data structure FDOMAIN_16X0 using
an undeclared function fdomain_16x0_release() in Linux 2.4.17-pre7.

This is not a problem for the kernel itself, but it breaks compilation of
pcmcia-cs-3.1.30 because the later uses structure FDOMAIN_16X0.

The fix is trivial - declare fdomain_16x0_release() the same way as other
non-static functions from fdomain.c.

Another partly related problem is a warning in fdomain.c:

fdomain.c: In function `fdomain_16x0_release':
fdomain.c:2045: warning: control reaches end of non-void function

I wonder if the patches that introduce warnings should be allowed in the 
stable branch?  Anyway, comparing with other SCSI drivers I see that 0 
should be returned and scsi_unregister(shpnt) should be called before 
that.

Here's the patch.  The part for fdomain.h is 100% safe and should be
applied ASAP.  The part for fdomain.c should be safe too but I'll
appreciate if somebody tests it on a real Future Domain controller.
