Subject: [PATCH 3/3] kobject: Delete an unnecessary variable initialisation in
 kobject_uevent_env()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 19 Dec 2023 16:03:39 +0100

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