[PATCH 1/3] mtd-rfd_ftl: Replace a variable initialisation by assignments in move_block_contents()

Show all headers | View raw

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.
