There's a preference in Linux to use:
key_ref = ERR_PTR(-error);
if (something)
goto error;
instead because it uses less vertical space. It might originally have been
promulgated by Linus, but I don't remember. Though you do have a point - your
way makes error handling less subject breakage from code rearrangement.
