[PATCH 3/3] mtdswap: Improve a size determination in mtdswap_erase_block()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 8 May 2017 16:51:30 +0200

Replace the specification of a data structure by a name for
a local variable as the parameter for the operator "sizeof" to make
the corresponding size determination a bit safer.
