Subject: [PATCH AUTOSEL 5.13 05/11] net: qede: Fix end of loop tests for list_for_each_entry
Date: Tue, 3 Aug 2021 07:43:46 -0400 [thread overview]
Message-ID: <20210803114352.2252544-5-sashal@kernel.org> (raw)
In-Reply-To: <20210803114352.2252544-1-sashal@kernel.org>
From: Harshvardhan Jha <harshvardhan.jha@oracle.com>
[ Upstream commit 795e3d2ea68e489ee7039ac29e98bfea0e34a96c ]
The list_for_each_entry() iterator, "vlan" in this code, can never be
NULL so the warning will never be printed.
