    Subject[PATCH 03/10] dm snapshot: Delete an unnecessary variable initialisation in snapshot_map()
    From
    Date
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Thu, 29 Sep 2016 08:00:29 +0200

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