Subject[PATCH 2/2] ASoC: cs42l56: Improve two size determinations in cs42l56_i2c_probe()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 23 Nov 2017 09:33:15 +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.
