Re: libfdt: Add some documenting comments in libfdt.h

So, like, the other day David Gibson mumbled:

This patch adds some internal documentation in libfdt.h, in the form
of comments on the error codes and some functions.  Only a couple of
functions are covered so far, leaving the documentation still woefully
inadequate, but hey, it's a start.

Signed-off-by: David Gibson <redacted>

Dave,

Sorry, I can't get this patch to apply either before or after
the previous patch.  Did I miss one?

Thanks,
jdl
