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

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the spi tree, today's linux-next build (powerpc
allyesconfig) produced these warnings:

drivers/spi/spi-imx.c: In function 'spi_imx_buf_rx_swap_u32':
drivers/spi/spi-imx.c:284:15: warning: unused variable 'bytes_per_word' [-Wunused-variable]
  unsigned int bytes_per_word;
               ^
drivers/spi/spi-imx.c: In function 'spi_imx_buf_tx_swap_u32':
drivers/spi/spi-imx.c:319:15: warning: unused variable 'bytes_per_word' [-Wunused-variable]
  unsigned int bytes_per_word;
               ^

Introduced by commit
