This makes the 'name' parameter unused now.
Which begs the question if it should be removed.
One other detail is that the device-tree will need to set a compatible
string to 'bmi088-accel' and this will work (for SPI devices) for all
chip-types (including the new ones).
This raises the question of whether we should update the new chips in
the DT yaml doc here?
Documentation/devicetree/bindings/iio/accel/bosch,bmi088.yaml
properties:
compatible:
enum:
- bosch,bmi088-accel
If yes, then the 'drivers/iio/accel/bmi088-accel-spi.c' file also
requires an update with the new device-names.
