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

usb: gadget: udc: renesas_usb3: fix number of the pipes

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: fix number of the pipes

This controller on R-Car Gen3 has 6 pipes that included PIPE 0 for control actually. But, the datasheet has error in writing as it has 31 pipes. (However, the previous code defined 30 pipes wrongly...)

Anyway, this patch fixes it.
