From 03aa29f80e371c75370e83eded7b551951385122 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Wed, 8 Jul 2015 16:54:13 +1000 Subject: [PATCH] m68k: fix io functions for ColdFire/MMU/PCI case The inb/outb/... family of IO methods end up being multiply defined when building PCI support for the ColdFire. Compiling gives this: CC init/main.o In file included from ./arch/m68k/include/asm/io.h:4:0, from include/linux/bio.h:30, from include/linux/blkdev.h:18, from init/main.c:75: ./arch/m68k/include/asm/io_mm.h:420:0: warning: "inb" redefined ./arch/m68k/include/asm/io_mm.h:108:0: note: this is the location of the previous definition ... The ColdFire/PCI case defines its own IO access methods, so no others should be defined or used in this case. Conditionally disable other definitions that clash with it.
