Subject: [PATCH 41/54] md/raid10: Improve another size determination in
 setup_conf()

From: Markus Elfring <elfring@...rs.sourceforge.net>

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.
