From 7a56c4168e4453732c35b1e33a683d91f04f379f Mon Sep 17 00:00:00 2001 From: Zhaoyang Liu Date: Fri, 5 Jun 2015 01:01:53 +0530 Subject: [PATCH] mwifiex: change debug dump issue since skb maybe null This patch fixes semantic warning for debugging data dump feature. Previous code is based on the assumption that skb is not null. New change makes sure that we already have data buffer.
