The point of moving the table to the individual drivers was that the
right one can get loaded automatically. This requires of course that
you put only one in there. It really needs to be
static const struct i2c_device_id pm800_id_table[] = {
{"88PM800", CHIP_PM800},
};
MODULE_DEVICE_TABLE(i2c, pm800_id_table);
and
static const struct i2c_device_id pm805_id_table[] = {
{"88PM805", CHIP_PM805},
};
MODULE_DEVICE_TABLE(i2c, pm805_id_table);
would update. thanks!

This can be written much shorter if you leave out the "88pm80?-objs:=" lines
and just build each module from one file as in
obj-$(CONFIG_MFD_88PM800) += 88pm800-core.o 88pm80x-i2c.o
It might make sense to drop the "core" and "i2c" postfixes on the names,
your choice.
would update. thanks!

I don't really like repeating myself, but this still contains a lot
of crap that needs to be moved out of this file, into the places
where it's used:
