debugfs code complained at boot time that debugfs: Directory 'reg-dummy-regulator-dummy' with parent 'regulator' already present! if we compile kernel with DEBUG_TEST_DRIVER_REMOVE. The problem is that we don't provide .remove() method for dummy_regulator_driver, which should invoke regulator_unregister() on device teardown to properly free things. Though it's harmless as dummy_pdev never gets unbound in practice, let's use devm_regulator_register() to get rid of the inconsistency.

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.
