From 32230ac1ccbd66f36bd6955eddc45fc06861c1b5 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 10 Sep 2016 09:55:53 +0200 Subject: ATM-ZeitNet: Use kmalloc_array() in start_tx() * 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.
