This is how my editor does the indention. I'm sure this can be changed,
but I want the indention only to depend on the logical structure not on
where the opening parenthesis in the previous line is. This saves
context changes for future patches.

Yeah, I like seperating the register bit field name from that fact that
the #define holds a mask.

I intentionally did that, as these two messages are related to the
console part of the serial driver while the rest of the messages are
about the serial/tty stuff. And I didn't like changing the definition of
pr_fmt in the middle of the file.
