5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@xxxxxxx>
commit 245f3b149e6cc3ac6ee612cdb7042263bfc9e73c upstream.
Update watermark will be done inside the hwfifo_set_watermark callback
just after the update_scan_mode. It is useless to do it here.
Fixes: 7f85e42a6c54 ("iio: imu: inv_icm42600: add buffer support in iio devices")
