[alsa-devel] [PATCH] ASoC: hdmi-codec: Use devm_kcalloc() in hdmi_codec_probe()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Wed, 26 Apr 2017 12:26:06 +0200

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "devm_kcalloc".

This issue was detected by using the Coccinelle software.
