Installed the proposed kernel in the hirsute on the machine dell precision 5760, reboot and check dmesg, there is no audio related error, open the gnome-sound-setting, the spk and internal mic work well, plug headset, the headphone and headset-mic work well too.

And this patch is already in the oem-5.10 kernel, for focal kernel, since focal kernel doesn't support soundwire audio, these 2 patches are useless for focal kernel. [Impact] The Dell precision 5760 is a TGL-H machine, and it has soundwire audio design, when running the hirsute kernel, the audio driver fails to load sof-firmware, then the whole audio fails to initialize and fails to work. [Fix] Backport 2 patches, these will remove hardcoded firmware name and allow load firmware according to the firmware name defined by pciid [Test] Booting the patched kernel, check dmesg, there is no errors about loading audio sof-firmware, playsound to spk and headphone, all worked well, record sound from internal mic and external mic, all worked well. [Where problems could occur] The patch remove the hardcoded firmware for all TGL soundwire machines, this could make the TGL soundwire machines fail to load the sof-firmware then the whole audio fail to work. But this possibiliy is low, since we tested the patches on different TGL soundwire machines, all worked well.
