From 5e78e465abcba4a21e5cc52bef41aa4b3361957d Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 25 Aug 2016 14:28:09 +0200 Subject: xtensa: ISS: Use kmalloc_array() in simdisk_init() * 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.
