I would suggest to not issue ERRs in such cases, as the API is designed to handle OOM
situations. I think it's enough to simply do:

    if (!physDev->allocatedSize) return FALSE;
...
    if (!mh) return FALSE;


We can not have ERRs all over the code where memory allocations fail, it would
clutter things way too much, and for almost no use.
