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

tty: always relink the port

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.

Subject: tty: always relink the port

If the serial device is disconnected and reconnected, it re-enumerates properly but does not link it. fwiw, linking means just saving the port index, so allow it always as there is no harm in saving the same value again even if it tries to relink with the same port.

Fixes fb2b90014d78 ("tty: link tty and port before configuring it as console")
