You don't have a .of_match table but according the DT bindings, the
compatible string "mediatek,mt6323-regulator" should be used so there
should be a OF match table or the vendor prefix of the compatible
string won't be used for matching (i.e: fallbacks to the driver .name
for match).

+module_platform_driver(mt6323_regulator_driver);

+MODULE_AUTHOR("Chen Zhong [off-list ref]");
+MODULE_DESCRIPTION("Regulator Driver for MediaTek MT6397 PMIC");

This alias should not be needed if you provide a OF match table and a
MODULE_DEVICE_TABLE(of, foo);

Best regards,
