This is a note to let you know that I've just added the patch titled
usb: gadget: f_sourcesink: Fix isoc transfer for USB_SPEED_SUPER_PLUS
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.

Currently when gadget enumerates in super speed plus, the isoc endpoint request buffer size is not calculated correctly. Fix this by checking the gadget speed against USB_SPEED_SUPER_PLUS and update the request buffer size.
