cppcheck warning:
sound/soc/soc-pcm.c:1907:6: style: Variable 'err' is assigned a value that is never used. [unreadVariable] err = dpcm_be_dai_hw_free(fe, stream); ^
it's not clear why dpcm_be_dai_hw_free() is sometimes called without testing the error status, and sometimes an error message is provided.
When in doubt, add an error message for consistency. This may have to be revisited.
