[alsa-devel] [PATCH 4/4] ASoC: wm2000: Improve a size determination in wm2000_i2c_probe()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Fri, 24 Nov 2017 08:18:14 +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.
