Hi Mark,

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

drivers/spi/spi-dw.c: In function 'dw_spi_setup':
drivers/spi/spi-dw.c:400:6: warning: unused variable 'ret' [-Wunused-variable]
  int ret;
      ^~~

Introduced by commit

  9400c41e77b8 ("spi: dw: Convert to use CS GPIO descriptors")
