The following reply was made to PR kern/53598; it has been noted by GNATS.

From: "matthew green" <>
Subject: PR/53598 CVS commit: src/sys/dev
Date: Tue, 18 Sep 2018 05:24:10 +0000

 Module Name:	src
 Committed By:	mrg
 Date:		Tue Sep 18 05:24:10 UTC 2018
 Modified Files:
 	src/sys/dev/pci: xhci_pci.c
 	src/sys/dev/usb: usb.c
 Log Message:
 deal with partial attach failures in usb_attach vs usb_detach aka PR 53598.
 - make sure xhci's sc->sc_ios is NULL if failure happens.
 - rearrange usb_attach() / usb_doattach() to make it simpler to clean up.
 - move usb_async_intr softint into usb_once_init().  previously, each USB
   controller would start a new one, and leave the old one leaked.
 - handle controller interrupts without a bus attached
