Hello build bot (Jenkins), Nico Huber, Patrick Georgi, Martin Roth, Frans Hendriks, David Hendricks, Paul Menzel, Angel Pons, Felix Held,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).

lint: checkpatch: Add SUSPICIOUS_CODE_INDENT test

This patch adds a new test to checkpatch that identifies cases where a
line after a conditional statement is incorrectly intended (possibly
indicating the mistake of forgetting to add braces), like this:

if (a)
   b;
   c;

Unfortunately, it seems like checkpatch is partially unmaintained in
upstream Linux at the moment with maintainers either not responding at
all or not even willing to look at new patches [1]. Since detecting this
error class is important to coreboot, let's just carry this feature
locally for now.
