Prior to commit bd5d54e4d49d ("iio: adc128s052: add ACPI _HID AANT1280"), the driver unconditionally used spi_get_device_id() to get the index into the adc128_config array. However, with that commit, OF-based boards now incorrectly treat all supported sensors as if they are an adc128s052, because all the .data members of the adc128_of_match table are implicitly 0. Our board, which has an adc122s021, thus exposes 8 channels whereas it really only has two.
