Donghun reports that a notebook that has an AMD Ryzen 5700U but supports S3 has problems with USB after resuming from suspend. The issue was bisected down to commit d1658268e439 ("usb: pci-quirks: disable D3cold on xhci suspend for s2idle on AMD Renoir"). As this issue only happens on S3, narrow the broken D3cold quirk to only run in s2idle.
