From mboxrd@z Thu Jan 1 00:00:00 1970 From: elfring@users.sourceforge.net (SF Markus Elfring) Date: Thu, 25 Aug 2016 18:07:05 +0200 Subject: [PATCH] ARM: pxa: Use kmalloc_array() in pxa_pm_init() Message-ID: <49864e7d-f786-9739-6d8c-4480ce228830@users.sourceforge.net> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Markus Elfring Date: Thu, 25 Aug 2016 18:01:37 +0200 * A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
