This didn't work...

...but this did - the sequence is important.
I wonder why this script isn't part of the driver source any more...

Don't know why I had to also change av7110.c, because I would have
expected the CONFIG_DVB_AV7110_FIRMWARE_FILE macro to be set in

but then at least it wasn't obvious to me...
