[Fix] Intel wrote patches to let sof driver to choose hda hdmi codec driver, then both hdmi on the laptop and on the docking station worked. [Test Case] ran the kernel with these patches, and in the userspace, we used the intel updated ucm, then the hdmi audio on the docking station worked. [Regression Risk] Low, Intel wrote the patches and told us to backport these patches. In addition, we already tested these patches with 4 oem project bugs, all worked well.
