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

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
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.
