From 61e9aab7a1930ae031d1b9d948837b5ffd8e3f5e Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Fri, 22 Aug 2014 14:33:18 +0200 Subject: [PATCH] ath10k: flush hif buffers before recovery Transport buffers weren't flushed and processed before queueing hw recovery request to mac80211. This could in theory result in an unwanted htt/wmi rx events being processed while mac80211 recovers the device and possibly interfere or even crash the system.
