[alsa-devel] [PATCH 4/4] ASoC: soc-pcm: Improve a size determination in dpcm_be_connect()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sun, 19 Nov 2017 21:02:20 +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.
