From 0bce04be442cf4d6e4ba9dac2f0a4c5ee88af5c5 Mon Sep 17 00:00:00 2001 From: Andreas Larsson Date: Tue, 6 Nov 2012 00:12:03 +0000 Subject: of/address: sparc: Declare of_address_to_resource() as an extern function for sparc again This bug-fix makes sure that of_address_to_resource is defined extern for sparc so that the sparc-specific implementation of of_address_to_resource() is once again used when including include/linux/of_address.h in a sparc context. A number of drivers in mainline relies on this function working for sparc. The bug was introduced in a850a7554442f08d3e910c6eeb4ee216868dda1e, "of/address: add empty static inlines for !CONFIG_OF". Contrary to that commit title, the static inlines are added for !CONFIG_OF_ADDRESS, and CONFIG_OF_ADDRESS is never defined for sparc. This is good behavior for the other functions in include/linux/of_address.h, as the extern functions defined in drivers/of/address.c only gets linked when OF_ADDRESS is configured. However, for of_address_to_resource there exists a sparc-specific implementation in arch/sparc/arch/sparc/kernel/of_device_common.c Solution suggested by: Sam Ravnborg Signed-off-by: Andreas Larsson Acked-by: Rob Herring Signed-off-by: David S.
