From 0f0d0ed0870eca21e36dc520d7d9be292c103f80 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 10 Sep 2016 10:21:15 +0200 Subject: [PATCH] ATM-ZeitNet: Replace one kzalloc() call by kcalloc() * The script "checkpatch.pl" can point information out like the following. WARNING: Prefer kcalloc over kzalloc with multiply Thus fix the affected source code place. * 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. * Delete the local variable "size" which became unnecessary with this refactoring.
