patch "usb: renesas_usbhs: fix the BCLR setting condition for non-DCP pipe" added to usb-linus

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

usb: renesas_usbhs: fix the BCLR setting condition for non-DCP pipe

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 the BCLR setting condition for non-DCP pipe

This patch fixes an issue that the driver sets the BCLR bit of {C,Dn}FIFOCTR register to 1 even when it's non-DCP pipe and the FRDY bit of {C,Dn}FIFOCTR register is set to 1.
