From 505a2e882bfae6627c84586edb276485df05c2ef Mon Sep 17 00:00:00 2001 From: Arend Van Spriel Date: Fri, 16 Dec 2016 11:21:54 +0000 Subject: [PATCH] nl80211: rework {sched_,}scan event related functions A couple of functions used with scan events were named with term "send" although they were only preparing the the event message so renamed those. Also remove nl80211_send_sched_scan_results() in favor of just calling nl80211_send_sched_scan() with the right value.
