A few update suggestions were taken into account
from static source code analysis.

Markus Elfring (2):
  Use kcalloc() in alloc_res_chunk_list()
  Use kcalloc() in usnic_vnic_alloc_res_chunk()

[PATCH 1/2] IB/usnic: Use kcalloc() in alloc_res_chunk_list()

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.
