As far as I can tell that's not true.  With FW_LOADER=n, firmware_class.c is
compiled out and request_firmware() always returns -EINVAL.  My patch tries to
make it more clear that FW_LOADER is the "top-level" option which covers all
three firmware loading mechanisms: built-in, directly from the filesystem, and
the user-mode helper.
