Subject: [PATCH] [net/sched]: Remove redundant condition in qdisc_graft
Date: Thu, 18 Jun 2020 00:00:56 -0400	[thread overview]
Message-ID: <20200618040056.30792-1-gaurav1086@gmail.com> (raw)
In-Reply-To: <20200618012308.28153-1-gaurav1086@gmail.com>

parent cannot be NULL here since its in the else part
of the if (parent == NULL) condition. Remove the extra
check on parent pointer.
