From 79dabbd505210e41c88060806c92c052496dd61c Mon Sep 17 00:00:00 2001 From: Zhang Lixu lixu.zhang@intel.com Date: Mon, 31 Mar 2025 13:50:22 +0800 Subject: [PATCH] iio: hid-sensor-prox: Fix incorrect OFFSET calculation

The OFFSET calculation in the prox_read_raw() was incorrectly using the unit exponent, which is intended for SCALE calculations.

Remove the incorrect OFFSET calculation and set it to a fixed value of 0.
