Subject: linux-next: build warning after merge of the moduleh tree

Hi Paul,

After merging the moduleh tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

block/bsg-lib.c:75:1: warning: data definition has no type or storage class
block/bsg-lib.c:75:1: warning: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL'

This is an interaction with commit aa387cc89567 ("block: add bsg helper
library") from the block tree.  That file should have included module.h
but now would need export.h it seems (just uses EXPORTSYMBOL_GPL).

I applied the following as a merge fix patch:
