Nope, the better fix is to use a different mechanism.

See commit acc8fa41ad31c5
("printk: add generic functions to find KERN_<LEVEL> headers")

and

commit 04d2c8c83d0e3a
("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern")

I'll submit that "better fix" shortly after Greg's update has
been pulled/merged by Linus.

cheers, Joe
