This is a note to let you know that I've just added the patch titled
usb: Don't die twice if PCI xhci host is not responding in resume
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: usb: Don't die twice if PCI xhci host is not responding in resume
usb_hc_died() should only be called once, and with the primary HCD
as parameter. It will mark both primary and secondary hcd's dead.
Remove the extra call to usb_cd_died with the shared hcd as parameter.
Fixes: ff9d78b36f76 ("USB: Set usb_hcd->state and flags for shared roothubs")
