If the camera is stopped\n these buffers are returned earlier in error state: complete the\n Request bypassing the IPA operations\n- As cancelled Requests might now be completed earlier then IPA events,\n modify the IPA event handler to ignore Requests that have been\n completed already\n\nSigned-off-by: Daniel Scally <dan.scally@ideasonboard.com>\nSigned-off-by: Jacopo Mondi
