From 20d717bb0ff8cf37eedc9edb538c6f7ddc2b44cc Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Fri, 19 Jul 2013 20:16:17 +0200 Subject: ath9k_htc: do some initial hardware configuration commit dc2a87f519a4d8cb376ab54f22b6b98a943b51ce upstream. Currently we configure harwdare and clock, only after interface start. In this case, if we reload module or reboot PC without configuring adapter, firmware will freeze. There is no software way to reset adpter. This patch add initial configuration and set it in disabled state, to avoid this freeze. Behaviour of this patch should be similar to: ifconfig wlan0 up; ifconfig wlan0 down.
