Subject[PATCH] bus: arm-ccn: Use devm_kcalloc() in arm_ccn_probe()
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 19 Apr 2017 09:12:43 +0200

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

This issue was detected by using the Coccinelle software.
