From bb602f8c61e289389e7c2af1b577303a841f6d34 Mon Sep 17 00:00:00 2001 From: Giuseppe Barba Date: Tue, 21 Jul 2015 10:35:42 +0200 Subject: [PATCH] iio: st-sensors: add support for single full scale device Some sensors could have only one full scale value. This means that the sensor hasn't a full scale register. This commit add a check on the configured full scale address to support such kind of sensors.
