The use case is when we boot the platform with bootconsole enabled. What

As part of console setup in serial driver it resets that hardware which
is a race condition to bootconsole using the same hardware. This
patch adds a check to see if there is bootconsole before reseting the hardware.
Am sure there are better ways to solve this, so marking this patch as
RFC. Any suggestions are welcome.
Isn't there some way to check and wait for the hardware to be unused
before we reset it?
I recall being able to overcome this "race condition" by removing the
printks in the serial driver setup. Does that work for you?
Good point,
Its possible that removing prints during the transition fixes the issue.
I will give it a try.
