[Qemu-devel] [PATCH v2 RFC] scripts/checkpatch.pl: add check for `while` and `for`

[Su Hang <suhang16@mails.ucas.ac.cn>]

Add check for `while` and `for` statements, which condition has more than
one line.

The former checkpatch.pl can check `if` statement, which condition has more
than one line, whether block misses brace round, like this:
'''
if (cond1 ||
    cond2)
    statement;
'''
But it doesn't do the same check for `for` and `while` statements.
