Subject: [PATCH 7/9] memstick: Improve another size determination in
 msb_read_boot_blocks()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 7 Jan 2017 20:00:16 +0100

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