Subject[PATCH 2/3] ASoC: cs42l73: Improve two size determinations in cs42l73_i2c_probe()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 22 Nov 2017 16:07:42 +0100

Replace the specification of two data structures by pointer dereferences
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.
