We always keep our mainline driver very close to our development trees. 
In the development trees we are updating the versions periodically and
we don't know which ones we are going to release publicly.

If we don't try to load newer versions when a kernel version is
released, and later decide to publish the newer firmware versions, it
won't work.  This is the explanation. :)

And actually, we try to load these newer firmwares, but if they are not
present, we fall back to the older one.  You can see that we correctly
loaded version 22 (the last line in your traces).

Now, these error messages to look annoying.  But fortunately Luis
Rodriguez is already attempting to fix that in another patch series.

HTH.
