This reverts commit7494e2e6c5. Which was upstream commitf2bd1c5ae2. The patch caused a regression leading to the missing HD-audio device with ASoC SOF driver. It was a part of large series and backporting it alone breaks things while backporting the whole is too intrusive as stable changes. And, the issue the patch tries to address is a corner case, hence it's better to revert.
