[PATCH] net: sched: use PTR_ERR_OR_ZERO macro in tcf_block_cb_register
From: Gustavo A. R. Silva
Date: Thu Jul 19 2018 - 00:16:09 EST
This line makes up what macro PTR_ERR_OR_ZERO already does. So,
make use of PTR_ERR_OR_ZERO rather than an open-code version.
This code was detected with the help of Coccinelle.
