Subject: checkpatch.pl bug for EXPORT_SYMBOL when struct initialization
 follows define

I believe I've found a bug in checkpatch.pl where an EXPORT_SYMBOL for
an initialized struct following a simple #define without an intervening
blank line falsely reports that EXPORT_SYMBOL doesn't follow the symbol
definition.  Here's an example:

	#define SOMETHING_ELSE 1
	struct blah foo = {
		.a = 1
	};
	EXPORT_SYMBOL(foo);

You can see from the debug print that the full statement has not been
identified.

	FOO A<+EXPORT_SYMBOL(foo);> stat<+      .a = 1
	 };> name<foo>

Unfortunately my perl skills were not sufficient to find a fix.

Thanks,
Joe
