ASoC: soc-compress: Fix and add DPCM locking
We find mising DPCM locking inside soc_compr_set_params_fe before calling dpcm_be_dai_hw_params() and dpcm_be_dai_prepare() which cause lockdep assert for DPCM lock not held in __soc_pcm_hw_params() and __soc_pcm_prepare() Signed-off-by: Shalini Manjunatha <quic_c_shalma@quicinc.com> Link: https://msgid.link/r/d985beeafdd32316eb45f20811eb7926da7a796e.1709720380.git.quic_c_shalma@quicinc.com Signed-off-by: Mark Brown <broonie@kernel.org>
