It makes the line characaters greater than 80. Shall I still add braces?
I mean it's better that I add them to prevent precedence issues, but it
adds another warning, hence I wasn't sure.

Generally speaking, it's ok to spread the macro body onto multiple
lines.
In this case, it would be better to replace this printk format type with
"%pad". See Documentation/core-api/printk-formats.rst
