This is a real problem we are facing here. It happens on PPC when all

It's because i2c-designware-core.c is used in two modules
(i2c-designware-platform and i2c-designware-pci) and KBUILD_MODNAME is
not defined for those because (scripts/Makefile.lib):
# $(modname_flags) #defines KBUILD_MODNAME as the name of the module
# it will end up in (or would, if it gets compiled in)
# Note: Files that end up in two or more modules are compiled
#       without the KBUILD_MODNAME definition. The reason is
#       that any made-up name would differ in different configs.

But DYNAMIC_DEBUG needs KBUILD_MODNAME for dev_dbg used in that source.

Any ideas? Why is it not a separate module for example?
