Subject: [PATCH 1/3] mtd-rfd_ftl: Replace a variable initialisation by assignments in move_block_contents()
Date: Thu, 31 Dec 2015 21:25:57 +0100	[thread overview]
Message-ID: <56858F55.7040604@users.sourceforge.net> (raw)
In-Reply-To: <56858E3A.7000706@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 31 Dec 2015 20:34:51 +0100

Replace an explicit initialisation for the variable "rc" at the beginning
by assignments that will only be performed if a memory allocation failed.
