From: Markus Elfring Date: Thu, 8 Sep 2016 12:20:17 +0000 (+0200) Subject: ATM-ENI: Use kmalloc_array() in eni_start() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d9e6620c8ee108f068cd703b3b82d9a8d38c1ada;p=linux-beck.git ATM-ENI: Use kmalloc_array() in eni_start() * 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 structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
