The first line of *.mod lists the object files that consist of the module. This may contain duplication if the same object is added multiple times, like this: obj-m := foo.o foo-$(CONFIG_FOO1_X) += foo1.o foo-$(CONFIG_FOO1_Y) += foo1.o foo-$(CONFIG_FOO2_X) += foo2.o foo-$(CONFIG_FOO2_Y) += foo2.o This is probably not a big deal. As far as I know, the only small problem is scripts/mod/sumversion.c parses the same file over again. This can be avoided by adding $(sort ...). It has a side-effect that sorts the objects alphabetically, but it is not a big deal, either.
