staging: wilc1000: check if device is initialzied before changing vif
When killing hostapd, the interface is closed which deinitializes the device, then change virtual interface is called. This change checks if the device is initialized before sending the interface change command to the device Signed-off-by: Adham Abozaeid <adham.abozaeid@microchip.com> Link: https://lore.kernel.org/r/20191028184019.31194-1-adham.abozaeid@microchip.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
