From c66ebf2db555c6ed705044eabd2b37dcd546f68b Mon Sep 17 00:00:00 2001 From: Pan Bian Date: Sat, 3 Dec 2016 21:49:08 +0800 Subject: net: dcb: set error code on failures In function dcbnl_cee_fill(), returns the value of variable err on errors. However, on some error paths (e.g. nla put fails), its value may be 0. It may be better to explicitly set a negative errno to variable err before returning.
