The regulator_get_optional() exists for cases where the driver needs do behave differently depending on some regulator supply being present or not, as we don't use this we can use the standard regulator_get() and rely on its handling of unspecified regulators. While the driver currently doesn't specify any loads the regulator framework was updated last year to only account for load of enabled regulators, so should the need appear it's better to apply load numbers during initialization that dynamically. With this the regulator wrappers have been reduced the become identical to the standard bulk API provided by the regulator framework, so use these instead of rolling our own.

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.
