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

    usb: gadget: udc: fsl: make use of new usb_endpoint_maxp_mult()

to my usb git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git

The patch will show up in the next release of the linux-next tree
