This is a note to let you know that I've just added the patch titled
serial: omap-serial: Move info message to probe function
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: omap-serial: Move info message to probe function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently the info message about a missing wakeirq for uart is printed
every time the serial driver's startup function is called. This happens
multiple times and not just once.
This can cause lots of extra messages at boot time, slowing things down. It is
caused by commit 2a0b965cfb6e (serial: omap: Add support for optional wake-up)
which was applied for v3.13-rc1.
This patch moves the infomessage to the probe function to display it
only once.
