Because it's inadequate. You can't guarantee that we ever loaded
firmware. The same hardware might maintain state over warm reboots but
not over suspend. We never loaded the firmware loader driver. We never
called request_firmware(). We have no way of knowing whether the device
is an older one that needs firmware loading, or a newer one which has it
in flash.
