patch "Revert "serial: uartps: Do not allow use aliases >=" added to tty-linus

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

Revert "serial: uartps: Do not allow use aliases >=

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: Revert "serial: uartps: Do not allow use aliases >=
MAX_UART_INSTANCES"

This reverts commit 2088cfd882d0403609bdf426e9b24372fe1b8337.

As Johan says, this driver needs a lot more work and these changes are only going in the wrong direction:
