Used PTR_RET function instead of IS_ERR and PTR_ERR.
Patch found using coccinelle.

Egads... How about
if (!IS_ERR(cmm_thread_ptr))
return 0;
rc = PTR_ERR(cmm_thread_ptr);
instead of the entire thing? out_kthread: is just past that return 0
and there's nothing else leading to it, so with that change the label
itself can go as well.
