[PATCH 06/15] iio: adc: ad7923: add the AD7927 to the SPI ID table

[Greg Kroah-Hartman]

From: Josef Bacik <josef@xxxxxxxxxxxxxx>

The binding describes the AD7927 as

  compatible = "adi,ad7927", "adi,ad7928";

The OF match takes the second string. The modalias of the SPI device is
made from the first one, "ad7927", which is not in the spi_device_id table:
spi_get_device_id() returns NULL and ad7923_probe() dereferences it for
the chip information. The module is not loaded automatically either, as the
uevent of an SPI device says "spi:ad7927".

Add the name, with the data of the AD7928.
