[PATCH 2/9] ASoC: fsl: fsl_dma: remove unused variable
From: Pierre-Louis Bossart
Date: Fri Feb 19 2021 - 18:32:32 EST
cppcheck warning:
sound/soc/fsl/fsl_dma.c:411:10: style: Variable 'channel' is assigned
a value that is never used. [unreadVariable]
channel = substream->stream == SNDRV_PCM_STREAM_PLAYBACK ? 0 : 1;
^
Removing this line shows the variable isn't needed any longer so
remove declaration as well.
