It seems all of the SPI drivers want to propagate fwnode (or of_node)
of the physical device to the SPI device. Make sure we don't duplicate
it over and over in each new driver (+2 in this cycle) by making core
to take care of that. Note, similar is done already by IIO and
I²C subsystems.

There is one noticeable and quite specific case that is taken care in
the first patch and would be nice to have a confirmation from Cirrus
that everything is okay. The rest is just a mechanical conversion.

Andy Shevchenko (4):
  spi: Propagate default fwnode to the SPI controller device
  spi: Drop duplicate of_node assignment
  spi: Drop duplicate fwnode assignment
  spi: Drop duplicate device_set_node() call
