[PATCH] libertas: split module into two (libertas.ko and usb8xxx.ko)
* add CONFIG_LIBERTAS to Kconfig * remove global variable libertas_fw_name, the USB module might want to use a different default FW name than the CF module, so libertas_fw_name is now local to if_usb.c * exported some symbols as GPL Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
