From 27b74cb39c999965610b6161e748320f0bc68a70 Mon Sep 17 00:00:00 2001 From: Carlos Song Date: Wed, 18 Jan 2023 15:42:25 +0800 Subject: [PATCH] iio: imu: fxos8700: fix failed initialization ODR mode assignment commit eb6d8f8705bc19141bac81d8161461f9e256948a upstream. The absence of correct offset leads a failed initialization ODR mode assignment. Select MAX ODR mode as the initialization ODR mode by field mask and FIELD_PREP.
