Okay, I checked the output of checkpatch.pl on those three commits and
I can confirm that checkpatch.pl warns during its own execution with:

Use of uninitialized value $1 in regexp compilation at
./scripts/checkpatch.pl line 2638.

Mrinal, can you debug and find out why and what specifically in those
patches cause this warning in line 2638?

Also, what is the intent and when was this introduced to
checkpatch.pl? It could be that it never worked since it was
introduced or that it broke due to some refactoring. Can you find what
happened in this case here?

Lukas
