From 15ac0778a65322c8c39eb2a6636218554d348690 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Sun, 10 Mar 2013 07:51:39 +0200 Subject: [PATCH] ath6kl: remove false check from ath6kl_rx() Dan found a check from ath6kl_rx() which doesn't make any sense at all: " 1327 if (status || !(skb->data + HTC_HDR_LENGTH)) { ^^^^^^^^^^^^^^^^^^^^^^^^^^ skb->data is a pointer. This pointer math is always going to be false. Should it be testing "packet->act_len < HTC_HDR_LENGTH" or something?" I don't know what the check really was supposed to do, but I think Dan's guess is right. Fix it accordingly.
