I see that you have upgraded to the new version.  :)  Some of the
error messages were already there before but the format changed
slightly.  Sorry about that.

There are a bunch of debug statements here.  Ignore them unless they
lead to a false positive.  Warnings and errors will all have "warn:"
or "error:" in the message.  I've removed the "debug: could not get
condition type" warning.

These also weren't sent to the kbuild list so I guess you already
you looked at them manually.

regards,
dan carpenter

Yes, after some delay. :)

No problem.

OK, I'll completely ignore all smatch debug messages from now on.

Yes.
