ASoC: soc-pcm: Don't zero TDM masks in __soc_pcm_open()
[ Upstream commit39bd801d69
] The DAI tx_mask and rx_mask are set by snd_soc_dai_set_tdm_slot() and used by later code that depends on the TDM settings. So __soc_pcm_open() should not be obliterating those mask values. The code in __soc_pcm_hw_params() uses these masks to calculate the active channels so that only the AIF_IN/AIF_OUT widgets for the active TDM slots are enabled. The zeroing of the masks in __soc_pcm_open() disables this functionality so all AIF widgets were enabled even for channels that are not assigned to a TDM slot.
