Alexandre Bounine 8347245750 rapidio/tsi721_dma: update error reporting from prep_sg callback ... Switch to returning error-valued pointer instead of simple NULL pointer. This allows to properly identify situation when request queue is full and therefore gives to upper layer an option to retry operation later.
