linux-next: build warning after merge of the slave-dma tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the slave-dma tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/dma/sun4i-dma.c: In function 'sun4i_dma_prep_dma_cyclic':
drivers/dma/sun4i-dma.c:30:51: warning: statement with no effect [-Wunused-value]
   30 | #define SUN4I_DMA_CFG_SRC_ADDR_MODE(mode) ((mode) << 5)
      |                                           ~~~~~~~~^~~~~
drivers/dma/sun4i-dma.c:701:8: note: in expansion of macro 'SUN4I_DMA_CFG_SRC_ADDR_MODE'
  701 |        SUN4I_DMA_CFG_SRC_ADDR_MODE(linear_mode);
      |        ^~~~~~~~~~~~~~~~~~~~~~~~~~~

Introduced by commit

  6ebb827f7aad ("dmaengine: sun4i: use 'linear_mode' in sun4i_dma_prep_dma_cyclic")

Please do not ignore/dismiss new warnings ... this one points out a real issue.
