[PATCH 5.10 069/139] iio: imu: fxos8700: fix failed initialization ODR mode assignment

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Carlos Song <carlos.song@xxxxxxx>

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.
