patch "USB: serial: console: fix use-after-free after failed setup" added to usb-linus

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

USB: serial: console: fix use-after-free after failed setup

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: console: fix use-after-free after failed setup

Make sure to reset the USB-console port pointer when console setup fails in order to avoid having the struct usb_serial be prematurely freed by the console code when the device is later disconnected.
