Subject: [PATCH] iio: hid-sensor-prox: Fix scale not correct issue
Date: Wed, 20 Jan 2021 15:49:35 +0800 [thread overview]
Message-ID: <20210120074935.26637-1-xiang.ye@intel.com> (raw)
Currently, the proxy sensor scale is zero because it just return the
exponent directly. To fix this issue, this patch use
hid_sensor_format_scale to process the scale first then return the
output.
