Subject: [PATCH 178/203] of: clean-up ifdefs in of_irq.h
|
||
|
|
|
||
|
|
Much of of_irq.h is needlessly ifdef'ed. Clean this up and minimize the
|
||
|
|
amount ifdef'ed code. This fixes some build warnings when CONFIG_OF
|
||
|
|
is not enabled (seen on i386 and x86_64):
|
||
|
|
|
||
|
|
include/linux/of_irq.h:82:7: warning: 'struct device_node' declared inside parameter list [enabled by default]
|
||
|
|
include/linux/of_irq.h:82:7: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default]
|
||
|
|
include/linux/of_irq.h:87:47: warning: 'struct device_node' declared inside parameter list [enabled by default]
|
||
|
|
|
||
|
|
Compile tested on i386, sparc and arm.
