[alsa-devel] [PATCH 2/2] ASoC: cs42l52: Improve two size determinations in cs42l52_i2c_probe()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Wed, 22 Nov 2017 22:11:30 +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.
