Mt6359 platform device is instantiated by mfd_add_devices(). In the case, dev->of_node is NULL so that always fails to get the regulator_dev. Use regualator-name "vaud18" that in dts node instead of "LDO_VAUD19-supply". So that we can get regulator_dev through regulator_lookup_by_name() directly.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
