Subject: [PATCH 1/2] sh-clk: Improve a size determination in
 sh_clk_fsidiv_register()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 16 May 2017 18:42:22 +0200

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.
