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.
Fixes: 26c78daade0f ("USB: io_ti: Add heartbeat to keep idle EP/416
ports from disconnecting")
