Subject: [PATCH 2/2] of_coresight: Use devm_kcalloc() in of_coresight_alloc_memory()
Date: Thu, 27 Apr 2017 21:47:38 +0200	[thread overview]
Message-ID: <f053b2f8-9c35-a5fc-5260-dfee273faf53@users.sourceforge.net> (raw)
In-Reply-To: <52619d05-65c4-149d-f355-cf9c037a0c9b@users.sourceforge.net>

From: Markus Elfring <elfring@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.
