patch "serial: txx9: add missing platform_driver_unregister() on error in" added to tty-linus

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

serial: txx9: add missing platform_driver_unregister() on error in

to my tty git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-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.
