Well, you repeated the explanation of what's wrong -- although I don't
see how it actually causes an _error_; it works here.

The problem is that the MODULE_DEVICE_TABLE(dmi, foo) line expands to...

extern const struct dmi_device_id __mod_dmi_device_table
__attribute__ ((unused, alias("foo")));

And 'struct dmi_device_id' doesn't exist -- what we have is 'struct

In practice, this doesn't seem to matter because we never ask the
compiler to look _inside_ that struct -- it's just like a forward
declaration of 'struct foo' and then using pointers to it.

But it looks like Alexey's managed to find a way to actually make a
compiler barf on it, so that increases the motivation to fix it
