After updating forward-porting the driver so that it runs on a more
recent version of the kernel, I tried to get it running.

I'm guessing that you expected the iio_input driver to be instantiated
by a board specific file. Is there any way to have it generically try
out all the IIO devices, similarly to pci_register_driver()? Or should I
do that in the hid-sensor-accel driver?
