linux-next: build warning after merge of the spi tree

[Stephen Rothwell]

Hi Mark,

After merging the spi tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/spi/spi-ti-qspi.c: In function 'ti_qspi_dma_xfer':
drivers/spi/spi-ti-qspi.c:398:21: warning: unused variable 'dma_dev' 
[-Wunused-variable]
  struct dma_device *dma_dev = chan->device;
                     ^

Introduced by commit

  1351aaeb50b2 ("spi: spi-ti-qspi: Use dma_engine wrapper for dma memcpy call")
