The impact should be minimun. Applied to lunar/linux-unstable. Thanks, -Andrea
AMD thinks it's a BIOS issue, and we should fix this in the BIOS. We're still working on this issue with AMD and ODM BIOS to see if we can fix this, and I'll submit v2 if we need this quirk later.

From: "Chia-Lin Kao (AceLan)" <acelan.kao@canonical.com> BugLink: https://launchpad.net/bugs/2007530 [Impact] When the xHC host controller[1022:1505] is runtime suspended, it can't be waken up and the devices connect to it will be lost. [Fix] Add the xHC ID to an existing quirk fixes the issue https://www.spinics.net/lists/kernel/msg4689370.html [Test] Verified by me and QA. [Where problems could occur] It disables disable a bit which is enable in sparse controller and do reset on resume. The impact should be minimun.
