[J] [PATCH 1/1] Revert "ASoC: soc-pcm: Don't zero TDM masks in __soc_pcm_open()"

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/2007798

This reverts commit 793e7ce5571a9213c7bc9bd5ea22a3394f4b4d6b.

When the PCM gets opened at second time, the audio playback becomes
silent.

Newer kernels that get this commit via stable update are unaffected.

Instead of finding the implicit dependency that may introduce new
regression, revert the offending commit to fix the issue.
