This is a note to let you know that I've just added the patch titled
serial: 8250_uniphier: fix error return code in uniphier_uart_probe()
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-next 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.)

Fix to return a negative error code from the port register error handling case instead of 0, as done elsewhere in this function.
