This is a note to let you know that I've just added the patch titled
media: usbtv: core: 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-next 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 also be merged in the next major kernel release
during the merge window.
If you have any questions about this process, please let me know.

Subject: media: usbtv: core: make use of new usb_endpoint_maxp_mult()
We have introduced a helper to calculate multiplier
value from wMaxPacketSize. Start using it.
