If there are no functional changes, indicating that on the commit log
will make the review much easier.

This minor change above should just be a separate patch. Its just noise
otherwise.

I'm at a loss reviewing this,  my lib/Kconfig.debug already has a config
DEBUG_FS.  But above I see it is being added for the very first time.
I'm sure there is some odd conditional which is obscuring this, can
this be explained in the commit log?
