patch "serial: core: mark port as initialized in autoconfig" added to tty-linus

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

serial: core: mark port as initialized in autoconfig

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: serial: core: mark port as initialized in autoconfig

This is a followup on 44117a1d1732 ("serial: core: mark port as initialized after successful IRQ change").
Nikola has been using autoconfig via setserial and reported a crash similar to what I fixed in the earlier mentioned commit. Here I do the same fixup for the autoconfig. I wasn't sure that this is the right approach. Nikola confirmed that it fixes his crash.
