How about changing the check so it only matches the
if/while/for/*for_each*/ thing when it's the first thing on a line _and_
has non-trivial whitespace in front. Then a function declaration as
static void test_for_each()
{
would not fire, nor would it if it were written in the other common style
static void
test_for_each()
{
?
Maybe there'd still be a problem at the call-sites
test_for_each();
this_is_not_indented;
but the ending semi-colon should actually make it appear as a loop with
an empty body (though that in itself might fire a different warning,
dunno if checkpatch has that kind of warnings). But in any case the
above should remove _some_ false positives.
