This is a note to let you know that I've just added the patch titled
USB: serial: cp210x: enable usb generic throttle/unthrottle
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.

Assign the .throttle and .unthrottle functions to be generic function in the driver structure to prevent data loss that can otherwise occur if the host does not enable USB throttling.
