It happens on PPC when all I2C_DESIGNWARE_PLATFORM, I2C_DESIGNWARE_PCI and DYNAMIC_DEBUG are set. 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? thanks, -- js suse labs -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
