This patch doesn't apply to qemu.git/master because it's based on your
v2 patch.
Please send a single v4 patch that combines v2 and v3 changes and can be
applied to qemu.git/master.
You can use "git rebase -i origin/master" to combine changes and put
them onto the latest origin/master. See the "fixup" and "squash"
commands in git-rebase(1)'s interactive mode for combining patches.
Thanks!

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.
Using `(?:...)` instead of `(...)` in regex pattern catch.
Because `(?:...)` is faster and avoids unwanted side-effect.

It's a nit, but for readability I would suggest indenting the line
above an extra tab or two to make it clear that it is part of the
condition rather than the block. (You can see other instances of
this in the file).
Otherwise:
