Subsystem: designware usb3 drd ip driver, the rest, usb subsystem · Maintainers: Thinh Nguyen, Linus Torvalds, Greg Kroah-Hartman

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

    usb: dwc3: gadget: always cleanup all TRBs

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.

If we stop earlier due to short packet, we will
not be able to giveback all TRBs.
