From a954380acde6adf584de76c41e1d520097820dd5 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Tue, 8 Oct 2019 16:20:07 -0700 Subject: [PATCH] net: taprio: Fix returning EINVAL when configuring without flags When configuring a taprio instance if "flags" is not specified (or it's zero), taprio currently replies with an "Invalid argument" error. So, set the return value to zero after we are done with all the checks.
