From 6112ea0862facaeaeab504ee01c0d04bcd22daaf Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sun, 9 Jan 2011 11:03:43 +0100 Subject: zorro: ZTWO_VADDR() should return "void __iomem *" ZTWO_VADDR() converts from physical to virtual I/O addresses, so it should return "void __iomem *" instead of "unsigned long". This allows to drop several casts, but requires adding a few casts to accomodate legacy driver frameworks that store "unsigned long" I/O addresses.
