      spi/s3c64xx: Log error interrupts · c2573128
      Mark Brown authored
      Although the hardware supports interrupts we're not currently using them
      at all since for small transfers the overhead is greater than that for
      busy waiting and for large transfers we have interrupts from the DMA.
      This means that if the hardware reports an error (especially one which
      might not stall transfer) we might miss it.
      
      Take a first pass at dealing with such errors by enabling the interrupt
      if we can and logging the errors if they happen. Ideally we'd report the
      error via the affected transfer but since we're in master mode it's very
      difficult to trigger errors at present and this code is much simpler.
