This driver only turns the power on at probe and off via a custom devm_add_action_or_reset() callback. The new devm_regulator_get_enable() replaces this boilerplate code. Note that in event of an error on the devm_regulator_get() the driver would have continued without enabling the regulator which is probably not a good idea. So here we handle any error as a reason to fail the probe(). In theory this may expose breakage on a platform that was previously papered over but it seems low risk.

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.
