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.
