Hi Greg,

After merging the driver-core tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from include/linux/kernel.h:23:0,
                 from include/linux/cache.h:4,
                 from include/linux/time.h:7,
                 from include/linux/stat.h:60,
                 from include/linux/module.h:10,
                 from drivers/infiniband/ulp/srp/ib_srp.c:35:
include/linux/dynamic_debug.h: In function 'ddebug_dyndbg_module_param_cb':
include/linux/dynamic_debug.h:112:3: error: expected ')' before 'PFX'

Caused by commit b48420c1d301 ("dynamic_debug: make dynamic-debug work
for module initialization") interacting with commit e0bda7d8c33e
("IB/srp: Use pr_fmt() and pr_err()/pr_warn()") from Linus' tree (added
before v3.4-rc1).

I have used the driver-core tree from next-20120430 for today.
