I think you can drop the message and make the patch to be last in the series,
so it can be easily abandoned (in case that decision will be made) without
throttling the rest. At the same time in the commit message explain that with
move to read_poll_timeout() we drop the seems redundant message. I'm fine with
that approach. But at the end of the day it's not that critical to the main
purpose, i.e. cleaning up the Exar serial driver.
