From 201e59e8f1437244e6203bfda5b8946f054d993e Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Mon, 3 Apr 2006 22:23:15 +1000 Subject: [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.
