These two patch is to solve problem found in the case of one BE is used by multiple FE. The error log "ASoC: Unable to apply rate constraint" will happen when be_substream->runtime is use after free. Which is due to BE not being hw_free/shutdown correctly. Also to resolve fe_substream->runtime is not constrained by BE dai symmetry property.
