From 9f287a1c3fffbc10360d7490f5361fff0255a93d Mon Sep 17 00:00:00 2001 From: Jeremy Fertic Date: Tue, 11 Dec 2018 17:55:01 -0700 Subject: [PATCH] staging: iio: adt7316: remove dac vref buffer bypass from adt751x The option to allow the external vref to bypass the reference buffer is only available for adt7316/7/8. Remove the attributes for adt751x as well as the chip->id checks from the show and store functions.
