Subject: [PATCH 2/3] ASoC: simple-card: Use devm_kcalloc() in
 asoc_simple_card_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 26 Apr 2017 14:32:12 +0200

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "devm_kcalloc".

This issue was detected by using the Coccinelle software.
