Please make this:

	static const struct i2c_device_id fd5121_id[] = {
		{ .name = "fd5121", .driver_data = chip_fd5121 },
		{ .name = "fd5123", .driver_data = chip_fd5123 },
		{ .name = "fd5125", .driver_data = chip_fd5125 },
		{ }
	};
	MODULE_DEVICE_TABLE(i2c, fd5121_id);

See e.g.
https://lore.kernel.org/lkml/20260515103150.164887-2-u.kleine-koenig@baylibre.com/
for the rationale.

Best regards
