From 7d245172675a66bf3dc7f8fa51e81f80559a40a3 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Sun, 17 Sep 2017 18:17:10 +0200 Subject: iio: common: st_sensors: check odr address value in st_sensors_set_odr() Do not try to configure sample frequency if the sensor do not export odr register address in register map. That change will be used to properly support LIS3DHH accel sensor.
