Yes liberal sprinkling of {} per coding style fixes it too. But given
that the if (!cond) ; else pattern is fairly common even outside of
drm it seems like not just graphics people think that little bit of
added robustness in iterator macros is worth it. Only reason I
bothered with this is because I've seen another open-coded version of
this pattern fly by.
Anyway I'm going on vacations for a few weeks now. Andy/Yisheng, I
guess if you want this it's up to you to haggle for a consensus around
this. If that doesn't happen I'm happy to keep it in drm headers.
