Subject: [PATCH 17/18] HID-debug: Delete an unnecessary variable
 initialisation in hid_resolv_usage()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 7 Feb 2017 20:12:09 +0100

The local variable "buf" will be set to an appropriate pointer
by the following statement. Thus omit the explicit initialisation
at the beginning.
