Subject: [PATCH 21/25] net: pxa168_eth: Use kcalloc() in two functions
Date: Mon, 17 Apr 2017 17:31:08 +0200 [thread overview]
Message-ID: <5afe517a-ac25-dae2-55b9-71bef428a389@users.sourceforge.net> (raw)
In-Reply-To: <d6f26bba-c678-5b66-4f5d-85f56d895190@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 17 Apr 2017 14:32:14 +0200
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.
