[Fix] Backport one patch from upstream. [Test] Boot the patched kernel on the machine, check dmesg, it loads the correct tplg, and test speaker and headset, all work well. [Where problems could occur] If it could introduce regression, it will be on the sdw codec matching for adl machines, then it will make the driver load wrong tplg and make output device and input device not work anymore. But this possibility is very low, we already tested the patch on some dell adl machines, no regression found.
