Subject: [PATCH net] net: qede: Fix end of loop tests for list_for_each_entry
Date: Sun, 25 Jul 2021 23:28:04 +0530 [thread overview]
Message-ID: <20210725175803.60559-1-harshvardhan.jha@oracle.com> (raw)
The list_for_each_entry() iterator, "vlan" in this code, can never be
NULL so the warning will never be printed.
Signed-off-by: Harshvardhan Jha <harshvardhan.jha@oracle.com>
