[PATCH] xhci: Apply XHCI_RESET_TO_DEFAULT quirk to ADL-N
From: Reka Norman
Date: Thu Oct 27 2022 - 01:34:27 EST
ADL-N systems have the same issue as ADL-P, where a large boot firmware
delay is seen if USB ports are left in U3 at shutdown. So apply the
XHCI_RESET_TO_DEFAULT quirk to ADL-N as well.
This patch depends on "xhci: Add quirk to reset host back to default
state at shutdown".
