Bug description:
BugLink: https://bugs.launchpad.net/bugs/1832299
The 0001-xxx.patch is for adding the ICL pciid, it is not in the bionic
kernel,
so bionic kernel needs two patches.
The 0002-xxx.patch is in the upstream from v5.2-rc1, it is needed for
b/c/d/e.
[Impact]
We have some cometlake machines, after installing the bionic kernel, the sound
can't work at all, we found the sound driver didn't load into the kernel.
[Fix]
After add the pciid in the pci_driver, the sound driver can be loaded and
sound
worked well.
[Test Case]
Boot the system and play sound or record sound, they all worked well
[Regression Risk]
Low. Adding new pciid, will not change existing functions.
