    Subject[PATCH 5.4 220/344] ASoC: SOF: Intel: hda-dai: fix compilation warning in pcm_prepare
    Date
    From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

    [ Upstream commit d873997192ddcacb5333575502be2f91ea4b47b8 ]

    Fix GCC warning with W=1, previous cleanup did not remove unnecessary
    variable.

    sound/soc/sof/intel/hda-dai.c: In function ‘hda_link_pcm_prepare’:

    sound/soc/sof/intel/hda-dai.c:265:31: warning: variable ‘hda_stream’
    set but not used [-Wunused-but-set-variable]
    265 | struct sof_intel_hda_stream *hda_stream;
    | ^~~~~~~~~~
