[Fix] Backport a tplg file which is specific to this mahcine [Test] Install the patched linux-firmware and boot the latest oem-5.14 kernel on the machine, check dmesg, it loads the correct tplg, and test speaker and headset, all work well. [Where problems could occur] This SRU is adding a new tplg file, it has no chance to introduce a regression. SRU template for linux [Impact] we have a Dell ADL laptop which has sdw audio, but there is no camera and no internal digital mic in this machine, the current soc driver can't work on this machine, it will load a wrong tplg without this patch, and the speaker and headset couldn't work. [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.
