I have also added the cover letter with the patch. Hence added the numbering
here.
OK I did not see the cover letter.

Yeah sounds reasonable. Will do it in the next patch set.

Sure. Instead of [%d] I will use '%d'. Thankyou.

For this hard limit, you should probably refer to the Qemu commit which
introduced this:
commit def337ffda34d331404bd7f1a42726b71500df22
Author: Peter Maydell <peter.maydell(a)linaro.org>
Date: Fri Apr 20 15:52:46 2018 +0100
serial-isa: Use MAX_ISA_SERIAL_PORTS instead of MAX_SERIAL_PORTS
You can add this information in the commit message and refer to
MAX_ISA_SERIAL_PORTS definition in Qemu with a comment here.
If in future in Qemu if we change the value of MAX_ISA_SERIAL_PORTS, we
can also make same changes here.
