Subject: [ 04/25] ath9k_htc: do some initial hardware configuration
Date: Thu, 8 Aug 2013 18:41:40 -0700 [thread overview]
Message-ID: <20130809013650.104983140@linuxfoundation.org> (raw)
In-Reply-To: <20130809013649.057678051@linuxfoundation.org>
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Oleksij Rempel <linux@rempel-privat.de>
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.
