This was in the original code, but there is a "ret = -ENOMEM;"
missing here, and again a couple lines down in the original code.


Or should that be -EIO instead of -ENOMEM? I'm not sure.

-ENXIO is usually used in such a case.

Thanks for the feedback. I won't be able to access my work machine until the end of the week, so I will fix it then.
