[PATCH 2/2] of_coresight: Use devm_kcalloc() in of_coresight_alloc_memory()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Thu, 27 Apr 2017 21:29:12 +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.
