Looks like I'm a little too late and outnumbered here, but I really don't like this. It moves us away from kernel style unnecessarily, which both makes importing code more cumbersome and adds cognitive load to the many of us that regularly work on both coreboot and Linux. I also agree with the vertical space issue Vadim mentioned -- source code lines aren't free (in your brain).
The "danger" of this should be an absolute non-issue if we have checkpatch, because it will just catch that. I also have to admit I saw a problem with this maybe once in 5 years, I'm really surprised that everyone thinks this is a big deal.
