** Description changed: + The sof-pci-dev and snd-soc-skl all contains the same pciid, if + the soc-skl is loaded ahead of sof-pci-dev, the sof driver will + not work anymore, in the oem project, we manually put the soc-skl + in the blacklist. + + 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-slk + 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.
