I think it's not okay.
The rationale to have printk(KERN_DEBUG …) here is to allow a
compilation with support of those messages independently on
DYNAMIC_DEBUG.
If you want to switch to DYNAMIC_DEBUG you have to carefully check what
is done under SERIAL_DEBUG_PNP.
git grep on current linux-next shows that SERIAL_DEBUG_PNP is an
orphan.
So, I would suggest to remove #ifdef.
