Subject: [PATCH 4/9] md/dm-table: Delete an unnecessary variable
 initialisation in dm_split_args()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 1 Oct 2016 07:37:27 +0200

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