This is a note to let you know that I've just added the patch titled
usb: gadget: udc: dummy: 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
in the usb-testing 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 be merged to the usb-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

We have introduced a helper to calculate multiplier
value from wMaxPacketSize. Start using it.

Wait, don't you need to subtract 1 here?
