[PATCH 2/3] mtdswap: Improve two size determinations in mtdswap_add_mtd()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Mon, 8 May 2017 16:18:49 +0200

Replace the specification of two data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
