These macros are no longer in module.h and module.h is no longer present everywhere. Call out export.h for the real users who are making use of these macros, or else we'll get things like: CC drivers/uwb/umc-drv.o drivers/uwb/umc-dev.c:42: warning: data definition has no type or storage class drivers/uwb/umc-dev.c:42: warning: type defaults to ‘int’ in declaration of ‘EXPORT_SYMBOL_GPL’ drivers/uwb/umc-dev.c:42: warning: parameter names (without types) in function declaration Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
