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

usb: renesas_usbhs: Fix receiving data corrupt on R-Car Gen3 with

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: renesas_usbhs: Fix receiving data corrupt on R-Car Gen3 with
dmac

Since R-Car Gen3 SoC has the USB-DMAC, this driver should set dparam->has_usb_dmac to 1. Otherwise, behavior of this driver and the usb-dmac driver will be mismatch, then sometimes receiving data will be corrupt.
