Subject: [PATCH 07/10] staging/irda/net: Delete an unnecessary variable
 initialisation in four functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 11 Oct 2017 22:26:00 +0200

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