original code is preserved.

Well, I thought this over and I think unless we change the Kconfig
and make the backend modules [p54pci, p54usb and p54spi]
module-only options, we have to go with request_firmware_nowait.
You see, if the p54* modules are compiled into the very bzImage:
The instant workqueue option wouldn't work because the device
might be initialized before the filesystem is. A combo approach
[delayed workqueue, when no userspacehelper is available and a
direct call to request_firmware (when it is availabe)] would
work too, but then we would be reimplementing
request_firmware_nowait ...
Christian,
Your point is well taken. I will rewrite this one. John was holding it for 3.5
anyway.
Do we still want to try for the legacy firmware if the primary is not available?
