No, just read the code, it does exactly the right thing.

If you do

for_each_compatible_node(node, NULL, "foo") {
	do_something(node);
}

then the reference count is held just as long as the do_something()
function is run, and if you do

for_each_compatible_node(node, NULL, "foo")
	if (conditional_func(node))
		break;

then the node variable will have the reference count.
