The integer return of sensor_submit should be void as the call is asynchronous and the response is meant to be delivered using RTIO APIs signaling that the submission completed with error or success. Change the function signature to void and fix all uses of the submit API, fixing some bugs in the process. Signed-off-by: Tom Burdick <thomas.burdick@intel.com>
