Subject: [PATCH 05/24] ste_dma40: Improve a size determination in
 d40_of_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 17 Sep 2016 08:28:05 +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.
