Thanks for taking care of this.
Changes since V1 [2]:

Note that this is technically a new V1 (or V3, depending on how you
count), since the V2 of the original patchset was what became
d11cc8c3c4b6 ("tty: serial: use uart_port_tx_limited()") and you are
reverting in 1/3.
Not that this should be cause for a resend, just wanted to mention it.
Best Regards,
Jonas
