[PATCH 3/4] ALSA: cs46xx: Improve a size determination in cs46xx_dsp_proc_register_scb_desc()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 13 Nov 2017 18:56:58 +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.
