From b321a38d2407c7e425c54bc09be909a34e49f740 Mon Sep 17 00:00:00 2001 From: Eva Rachel Retuya Date: Sun, 9 Oct 2016 00:05:39 +0800 Subject: [PATCH] staging: iio: ad7606: fix improper setting of oversampling pins 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.
