Subject: xhci-pci: Only run d3cold avoidance quirk for s2idle
From: Mario Limonciello <mario.limonciello@xxxxxxx>
commit 2a821fc3136d5d99dcb9de152be8a052ca27d870 upstream.
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.
Fixes: d1658268e439 ("usb: pci-quirks: disable D3cold on xhci suspend for s2idle on AMD Renoir")
