Recent changes in udev are causing problems for drivers that load firmware from the probe routine. As b43 has such a structure, it must be changed. As this driver loads more than 1 firmware file, changing to the asynchronous routine request_firmware_nowait() would be complicated. In this implementation, the probe routine starts a delayed_work queue that calls the firmware loading routines when the delay (1 sec) expires..
