[PATCH 44/47] block-rbd: Delete an unnecessary initialisation in do_rbd_add()

Show all headers | View raw

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 12 Sep 2016 20:04:31 +0200

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