Subject: [PATCH 06/10] dm snapshot: Delete an unnecessary variable initialisation in snapshot_ctr()
Date: Thu, 29 Sep 2016 11:14:19 +0200 [thread overview]
Message-ID: <882f19c7-7013-a0e7-6385-d6d19aa4e51b@users.sourceforge.net> (raw)
In-Reply-To: <080668d9-1e1e-e208-f9ea-ff718e8070e5@users.sourceforge.net>

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