From: Rusty Russell <rusty@rustcorp.com.au>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit cff26a51da5d206d3baf871e75778da44710219d upstream.

MODULE_DEVICE_TABLE() calles MODULE_GENERIC_TABLE(); make it do the
work directly.  This also removes a wart introduced in the last patch,
where the alias is defined to be an unknown struct type "struct
type##__##name##_device_id" instead of "struct type##_device_id" (it's
an extern so GCC doesn't care, but it's wrong).

The other user of MODULE_GENERIC_TABLE (ISAPNP_CARD_TABLE) is unused,
so delete it.

Bryan: gcc v3.3.2 cares
