Ideally, coccinelle would strip unnecessary braces too. But I do not see any option in coccinelle for this, so instead, I edited the patch text using search&replace to remove the braces. Unfortunately this is not fully automatic, in particular it didn't deal well with if-else-if-else blocks and ifdefs, so there is an increased likelikehood be some bugs in such spots. I also removed part of the patch that coccinelle generated for udev, where we returns -1 for failure. This should be fixed independently.
