Subject: [PATCH 3/4] netlink: Delete an unnecessary variable initialisation in
 __netlink_kernel_create()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 31 Dec 2023 17:45:00 +0100

The variable “listeners” will eventually be set to an appropriate pointer
a bit later. Thus omit the explicit initialisation at the beginning.
