From 253c6daa343104c1278facd11cb5ecfc7554fb38 Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Thu, 7 Nov 2013 14:18:25 +0100 Subject: caif: use pskb_put() instead of reimplementing its functionality Also remove the warning for fragmented packets -- skb_cow_data() will linearize the buffer, removing all fragments.
