Since the series that fixes console probe delay based on stdout-path[1] got
pulled into driver-core-next, I made these patches on top of them.

Even if stdout-path isn't set in DT, this patch should take console
probe times back to how they were before the deferred_probe_timeout
clean up series[2].

Fabio/Ahmad/Sascha,

Can you give this a shot please?

This series works fine for me (with and without stdout-path), thanks:

Are you sure it's only limited to the serial drivers?
(just asking, I don't know myself the answer)
