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.
