[gregkh]

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

    usb: cdnsp: Fix incorrect status for control request

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: cdnsp: Fix incorrect status for control request

Patch fixes incorrect status for control request.
Without this fix all usb_request objects were returned to upper drivers
with usb_reqest->status field set to -EINPROGRESS.
