Dang, Stephen notices that, too. TIL if I only do:

	make allmodconfig drivers/siox/

a missing EXPORT_SYMBOL doesn't make the build fail.

I squashed 

diff --git a/drivers/siox/siox-core.c b/drivers/siox/siox-core.c
index ae103349c91a..24a45920a240 100644

 	return smaster;

 {

into the offending commit in my above branch and did some more extensive
build testing.

Sorry
Uwe
