Subject[PATCH 2/2] ASoC: cs35l34: Improve two size determinations in cs35l34_i2c_probe()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 22 Nov 2017 21:17:42 +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.
