From 5f25b41f7ec242fce43d0f745369c0ba9d25cb72 Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Fri, 7 Mar 2014 07:44:00 +0000 Subject: [PATCH] iio: hid-sensor-magn-3d: Fix return values IIO_CHAN_INFO_SAMP_FREQ and IIO_CHAN_INFO_HYSTERESIS cases ignored the actual return values (which could be -EINVAL) and instead returned IIO_VAL_INT_PLUS_MICRO always. Return the actual value obtained from the functions. Both functions return IIO_VAL_INT_PLUS_MICRO upon success.
