That looks like a false positive I'll leave for Andy.

$ cat ~/export_symbol.c
int test_export_no_comment;
EXPORT_SYMBOL(test_export_no_comment);
int test_export_comment_int;		/* comment int */
EXPORT_SYMBOL(test_export_int);
int test_export_comment_symbol;
EXPORT_SYMBOL(test_export_symbol);	/* comment symbol */
int test_export_both;			/* comment both 1 */
EXPORT_SYMBOL(test_export_both);	/* comment both 2 */
$

Something's a bit off with the $stat variable:

test_export_int doesn't match the EXPORT_SYMBOL test.
test_export_symbol and test_export_both get warnings.
