Error in ERR_PTR usage

Was trying to understand ERR_PTR and friends and surprisingly the first 2 references via LXR seem to be erroneous. Did grep and found 1 additional incorrect reference "return ERR_PTR(0)" and another "ERR_PTR(PTR_ERR(p))" usage. Please let me know if this patch is good. If need be, I can chop it up for the individual maintainers, but it would be nice if someone can comment first.

Thanks,
Rayan
