We need to backport the this commint, this is already backported to 5.4 focal kernel, but it is not in the eoan kernel yet:
commit 8ce1cbd6ce0b1bda0c980c64fee4c1e1378355f1 Author: Jaroslav Kysela <pe...@perex.cz> Date: Wed Jan 22 20:07:52 2020 +0100 ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization order The code which checks the return value for snd_soc_add_dai_link() call in soc_tplg_fe_link_create() moved the snd_soc_add_dai_link() call before link->dobj members initialization. While it does not affect the latest kernels, the old soc-core.c code in the stable kernels is affected. The snd_soc_add_dai_link() function uses the link->dobj.type member to check, if the link structure is valid. Reorder the link->dobj initialization to make things work again. It's harmless for the recent code (and the structure should be properly initialized before other calls anyway). The problem is in stable linux-5.4.y since version 5.4.11 when the upstream commit 76d270364932 was applied.

From kernel-5.4 (focal kernel), the driver soc-skl is disabled by default, and there is no users report any issues on it. So let us disable soc-skl in the eoan and osp1 kernel too. The patch for eoan kernel doesn't remove the modules because looks like the abi folder are not controlled by git. This will break the modulecheck, so if this patch could be merged, please help remove those modules: snd-soc-skl snd-soc-skl-ipc snd-soc-skl-ssp-clk [Impact] If soc-skl driver is loaded ahead of sof driver, the sof could not work anymore, we need to blacklist the soc-skl manually [Fix] Like the focal kernel, we disable the soc_skl driver in the kernel config [Test Case] Tested on Lenovo and Dell machines which has dmic, the sof driver could be loaded successfully. Tested on the machinces without the dmic, the legacy hda driver worked well as before. [Regression Risk] Low, Focal kernel and mainine-5.5, 5.6-rc kernel all disabled this dirver; and We have not met a machine need the soc_skl driver yet; and Intel claim that the sof could replace the soc_skl driver. Probably a kernel bug. The sound card isn't detected in 5.3.0-41-generic Booting 5.3.0-40-generic does work.
