Subject: [PATCH 1/5] ISDN-CAPI: Use kmalloc_array() in capidrv_addcontr()
Date: Sun, 25 Sep 2016 13:11:13 +0200 [thread overview]
Message-ID: <f3c51d3b-ee3e-f877-40c2-898221ff0e67@users.sourceforge.net> (raw)
In-Reply-To: <be07f84d-fc84-e47d-207e-aedd8c960151@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 25 Sep 2016 11:06:17 +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 "kmalloc_array".
This issue was detected by using the Coccinelle software.
