Hi Josh
Thanks for the patch, but I'll ask you to fix the same thing in it, that
I've fixed for you in the first patch in this series:

Please, use error label names consistently. As you can see, currently the
driver uses the convention
ret = do_something();
if (ret < 0)
goto err_do_something;
i.e., the label is called after the operation, that has failed, not after
the clean up step, that the control now has to jump to. Please, update
your patch to also use this convention.
Thanks
