The logic of DMA completion is broken now since test_and_clear_bit() never returns the other bit is set. It means condition are always false and we have spi_finalize_current_transfer() called per each DMA completion which is wrong. The patch fixes logic by clearing BUSY bit first and then check for the other one. Fixes: 30c8eb52 (spi: dw-mid: split rx and tx callbacks when DMA) Signed-off-by: NAndy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: NMark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
