    Subject[ 035/102] ath9k_htc: do some initial hardware configuration
    Date
    3.10-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.
