Once again:
_this will break at link time if two such modules are included
statically into the kernel_
obj-$(CONFIG_W1_DS9490) += ds9490r.o
ds9490r-objs := dscore.o
obj-$(CONFIG_W1_FOO) += foo.o
foo-objs := dscore.o
This will break with CONFIG_W1_DS9490=y and CONFIG_W1_FOO=y.
That drivers/w1/ contains many EXPORT_SYMBOL's with no in-kernel users
is a different issue I might send a separate patch for (that besides
proprietary modules there might come some day open source drivers using
them is not a reason).
