I guess you haven't had the chance to take a look at this.  Or maybe you 
took a look at the kselftest harness macro mess and just decided not to 
say anything ;-)  I did look, after not hearing back, and the way those 
macros are used would make it a big and painful lift to straighten out - 
definitely not something for the -rc time frame.

So in the short term, I'm planning to take this as a fix to deal with the 
immediate issue.

checkpatch.pl clearly needs to be patched to assume that these kselftest 
harness macros don't follow the rules.  Care to take that on?
