This is a note to let you know that I've just added the patch titled
USB: core: fix device node leak
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-next 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 also be merged in the next major kernel release
during the merge window.
If you have any questions about this process, please let me know.

Subject: USB: core: fix device node leak
Make sure to release any OF device-node reference taken when creating
the USB device.
Note that we currently do not hold a reference to the root hub
device-tree node (i.e. the parent controller node).
