[PATCH] checkpatch: comments are whitespace for the purposes of finding the next line

[Andy Whitcroft]

While parsing statements we are recording the nominal next line for the
purposes of checking that EXPORT* follows exactly on below an appropriate
statement.  Where there is whitespace after a statement end marker (such
as ;) we will move to the next line.  This also needs to apply to inline
comments at the end of a line.

Allows us to more correctly parse:

    +int test_export;
    +EXPORT_SYMBOL(test_export);    /* No Error ! */
    +
    +int test_export2;    /* No Error below */
    +EXPORT_SYMBOL(test_export2);
    +
    +int test_export3;    /* Error below */
    +EXPORT_SYMBOL(test_export3);    /* Error ! */
    +
