Subject: [PATCH 20/39] netfilter: ipset: Use kmalloc() in comment extension helper

From: Jozsef Kadlecsik <kadlec@...ckhole.kfki.hu>

Allocate memory with kmalloc() rather than kzalloc(): the string
is immediately initialized so it is unnecessary to zero out
the allocated memory area.

Ported from a patch proposed by Sergey Popovich <popovich_sergei@...l.ua>.
