Subject: [PATCH 1/3] ASoC: simple-card: Use devm_kcalloc() in asoc_simple_card_parse_aux_devs()
Date: Wed, 26 Apr 2017 15:04:11 +0200	[thread overview]
Message-ID: <8c8c6979-0368-9ef5-2e10-57199f0bc03e@users.sourceforge.net> (raw)
In-Reply-To: <8b5e37d1-17c5-4551-801f-ca7939d5efd7@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 26 Apr 2017 14:21:51 +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.
