[PATCH] libertas: split wlan_add_card()
Split wlan_add_card() into a part that just setups kernel parameters and into the function libertas_activate_card(), which will implizitly use hardware functions by the started thread. This allows us later to do something like this: priv = libertas_add_card(); priv->hw_command_to_host = if_usb_command_to_host; priv->hw_xxxx = if_usb_xxxx; priv->hw_yyyy = if_usb_yyyy; wlan_activate_card() and of course the CF driver can set it's own functions.
