Subject[PATCH 07/10] dlm: Use kmalloc_array() in make_member_array()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 6 May 2017 09:19:17 +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.

* Replace the specification of a data type by a pointer dereference
to make the corresponding size determination a bit safer according to
the Linux coding style convention.
