From 5107d16e0aa4f56925c1627830c0e901782350df Mon Sep 17 00:00:00 2001 From: Jeremy Fertic Date: Tue, 11 Dec 2018 17:54:59 -0700 Subject: [PATCH] staging: iio: adt7316: use correct variable in DAC_internal_Vref read The dac internal vref settings are part of the ldac config register rather than the dac config register. Change the variable being used so the read returns the correct result. Whilst a fix, it is for a driver in heavy churn so do not backport to stable without taking considerable care and testing.
