Subject: [PATCH 2/2] i2c-nomadik: Improve a size determination in
 nmk_i2c_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 2 Feb 2018 16:28:20 +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.

This issue was detected by using the Coccinelle software.
