From 634349bae0b2a23f71cabbdb770d35fffc1aad8c Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Thu, 3 Sep 2015 10:43:45 +0200 Subject: [PATCH] ath10k: move hw_scan worker queuing The remain_on_channel callback needs different timeout. Calling ieee80211_queue_work() with a shorter delay after calling it with a longer delay will not change the timer. This caused the offchannel timeout worker to not trigger in time and caused the device to stay on channel longer then expected. This could cause some problems and was be easily reproduced with `iw offchannel` command.
