  ASoC: sh: dma-sh7760: remove unused variable
  ASoC: sh: rcar: align function prototypes
  ASoC: sh: rcar: simplify return
  ASoC: sh: rcar: core: rename shadowing variables
  ASoC: sh: rcar: ctu: add  missing error check
  ASoC: sh: rcar: ssi: remove redundant assignment
  ASoC: sh: siu_pcm: remove useless assignment
  ASoC: sh: siu_pcm: remove unused variable
