From f1e3e0515646dd0f4c783c1c39839d2706501344 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 6 Feb 2013 23:57:57 +0100 Subject: mac80211: remove IEEE80211_HW_SCAN_WHILE_IDLE There are only a few drivers that use HW scan, and all of those don't need a non-idle transition before starting the scan -- some don't even care about idle at all. Remove the flag and code associated with it. The only driver that really actually needed this is wl1251 and it can just do it itself in the hw_scan callback -- implement that.
