Have you checked this:
http://git.kernel.org/?p=linux/kernel/git/jaswinder/linux-2.6-tip.git;a=commitdiff;h=1ae843834668af3a30484e256fb27dc1a49f59cb

These leads to warnings:
 WARNING: EXPORT_SYMBOL(foo); should immediately follow its function/variable
 WARNING: EXPORT_SYMBOL(foo); should immediately follow its function/variable

So we have two options:
1. which I already shown above
2. remove these comments

Please let me know, which option you will prefer.
