Subject: staging: iio: ad7606: fix improper setting of oversampling pins

From: Eva Rachel Retuya <[email protected]>

commit b321a38d2407c7e425c54bc09be909a34e49f740 upstream.

The oversampling ratio is controlled using the oversampling pins, OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control bit.

The gpio connected to the OS2 pin is not being set correctly, only OS0 and OS1 pins are being set. Fix the typo to allow proper control of the oversampling pins.

Fixes b9618c0 ("staging: IIO: ADC: New driver for AD7606/AD7606-6/AD7606-4")
