dynamic_debug: use printk(KERN_WARNING..) in stub function
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. 2084c2084 < printk("<4>" PFX "dyndbg supported only in " "CONFIG_DYNAMIC_DEBUG builds\n") Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
