patch "USB: serial: io_ti: fix I/O after disconnect" added to usb-linus

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

USB: serial: io_ti: fix I/O after disconnect

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.

Subject: USB: serial: io_ti: fix I/O after disconnect

Cancel the heartbeat work on driver unbind in order to avoid I/O after disconnect in case the port is held open.

Note that the cancel in release() is still needed to stop the heartbeat after late probe errors.
