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.
