linux-next: build warning after merge of the sound-asoc tree

Hi all,

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

sound/soc/intel/boards/cht_bsw_rt5645.c: In function 'cht_codec_init':
sound/soc/intel/boards/cht_bsw_rt5645.c:265:22: warning: unused variable 'codec_dai' [-Wunused-variable]
  struct snd_soc_dai *codec_dai = runtime->codec_dai;
                      ^

Introduced by commit

  7bde09dfcf60 ("ASoC: Intel: cht-bsw-rt5645: fix DAI formats")
