patch "usb: gadget: udc: renesas-usb3: clear VBOUT bit in DRD_CON" added to usb-linus

[<gregkh@linuxfoundation.org>]

This is a note to let you know that I've just added the patch titled

    usb: gadget: udc: renesas-usb3: clear VBOUT bit in DRD_CON

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: gadget: udc: renesas-usb3: clear VBOUT bit in DRD_CON

This driver should clear the bit. Otherwise, the VBUS will output
wrongly if the usb port on a board has VBUS output capability.

		      Renesas USB3.0 peripheral controller")
