From 2e761b5a5222071d55ebccf65f93d281e4c11958 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Wed, 2 Oct 2013 11:03:40 +0200 Subject: [PATCH] ath10k: remove ce_sendlist_send It is completely pointless to keep this function around. It doesn't do anything different than ce_send except it introduces more overhead.
