commit bedb2ccb566de5ca0c336ca3fd3588cea6d50414 upstream.
In case of error in the bmi323_trigger_handler() function, the function exits without calling the iio_trigger_notify_done() which is responsible for informing the attached trigger that the process is done and in case there is a .reenable(), to call it.
