3.16.72-rc1 review patch. If anyone has any objections, please let me know.
Unless to enable applying further patches, I doubt there is ever a need to have any of Markus Elfring's patches applied to any -stable kernel.

commit 057ac1acdfc4743f066fcefe359385cad00549eb upstream.
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.
