Currently we are checking if the function returns nonzero. This is fine, however it adds a lot of bloat, for example the late_init initcall is practically never used and is only a stub function that returns zero. So - add a proper initcall macro to prepare for cleaning up unused stubs. Signed-off-by: Igor Belwon <igor.belwon@mentallysanemainliners.org>
