Subject: [PATCH 3/4] hwmon-nct6775: Use devm_kcalloc() in nct6775_create_attr_group()
Date: Thu, 27 Apr 2017 11:30:33 +0200	[thread overview]
Message-ID: <e5dc9467-16c5-a143-f8d5-4da464cd97f6@users.sourceforge.net> (raw)
In-Reply-To: <2f58a509-4aba-5c44-bc79-568b260ab692@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 27 Apr 2017 10:35:36 +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.
