drivers/infiniband/ulp/srp/ib_srp.c #defines pr_fmt() PFX fmt, but PFX
is not #defined until after <linux/*> headers are included.
This results in a bad expansion of the pr_warn() in the stub function.

< printk("<4>" PFX "dyndbg supported only in " "CONFIG_DYNAMIC_DEBUG builds\n")

> printk("<4>" "guano" "dyndbg supported only in " "CONFIG_DYNAMIC_DEBUG builds\n")
(END)
While that use-case is less than ideal, it will probably happen again,
and its easy to avoid by using raw printk().
