During our weekly CI tests of rt-devel branch we noticed that commit
78f4b59c6faa ("printk: Update the printk series.") breaks booting on
multiple NXP i.MX platforms (arm and arm64), likely related to
drivers/tty/serial/imx.c.

We are not planning any additional investigation at the moment and
we have no debug outputs to share, just wanted to give you a head-up.
