Independently on a) would we use some macro for condition, or b) fix
macros against this kind of nested conditions, there is another
weirdness we would like to avoid, i.e.

for_each_foo() {
 ...
} else {
 ...
}

It is written according to coding style, but too much weird.

So, summarize this discussion I think we would
- keep for_each_if() in DRM subsystem alone
- fix macros which are using positive condition 'if (cond)' by replacing
with 'if (!cond) {} else' form for sake of robustness.

Do you agree on that?
