[PATCH] powerpc: make ISA floppies work again
We used to assume that a DMA mapping request with a NULL dev was for ISA DMA. This assumption was broken at some point. Now we explicitly pass the detected ISA PCI device in the floppy setup. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
