From: Alberto Mattea <alberto@xxxxxxxxxxx> commit 16263abc12d09871156a1c8650fb651f0e552f5e upstream. This controller timeouts during suspend (S3) with [ 240.521724] xhci_hcd 0000:30:00.3: WARN: xHC save state timeout [ 240.521729] xhci_hcd 0000:30:00.3: ERROR mismatched command completion event thus preventing the system from entering S3. Moreover it remains in an undefined state where some connected devices stop working until a reboot. Apply the XHCI_SUSPEND_DELAY quirk to make it suspend properly.
