Thanks Andi.

I wonder how these tabs came in.
I am almost sure they were not in my original patch. But as git-send-email
do not save copies of my sent mails I cannot be sure.

Ingo - do you have a script on your side that could have converted
the spaces to tabs?
It could be a simple "make checkpatch happy" change too - but in this case
it was wrong.

Leading tabs in Makefiles that are not in front of commands are a typical
source of non-so-easy-to-debug problems.
Been there before....
