This is a note to let you know that I've just added the patch titled
usb: xhci: Clear XHCI_STATE_DYING on start
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: xhci: Clear XHCI_STATE_DYING on start
For whatever reason if XHCI died in the previous instant
then it will never recover on the next xhci_start unless we
clear the DYING flag.
