From e9bb0aa39bce2f0a159c562c322c2d2746e6560d Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Sun, 8 Sep 2013 18:36:11 +0300 Subject: ath10k: delete struct ce_sendlist struct ce_sendlist is useless as we always add just one buffer onto it. And most importantly, it's ugly as it doesn't use skb properly.
