[PATCH 11/14] RDMA/cxgb4: Use kcalloc() in create_qp()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 8 Feb 2017 20:27:51 +0100

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.
