 Use devm helpers for regulator get and enable 
Merge series from Matti Vaittinen <mazziesaccount@gmail.com>:

Use devm helpers for regulator get and enable

NOTE: The series depends on commit
ee94aff262 ("Devm helpers for regulator get and enable")
which currently sits in Mark's regulator/for-next

A few* drivers seem to pattern demonstrated by pseudocode:

- devm_regulator_get()
- regulator_enable()
- devm_add_action_or_reset(regulator_disable())

devm helpers for this pattern were added to remove bunch of code from
drivers. Typically following:

- replace 3 calls (devm_regulator_get[_optional](), regulator_enable(),
  devm_add_action_or_reset()) with just one
  (devm_regulator_get_enable[_optional]()).
- drop disable callback.

I believe this simplifies things by removing some dublicated code.

This series reowrks a few drivers. There is still plenty of fish in the
sea for people who like to improve the code (or count the beans ;]).

Finally - most of the converted drivers have not been tested (other than
compile-tested) due to lack of HW. All reviews and testing is _highly_
appreciated (as always!).

Revision history:

v3:
	- Drop already applied helper patches
	- Add a few more drivers

RFCv1 => v2:
	- Add devm_regulator_bulk_get_enable() and
	  devm_regulator_bulk_put()
	- Convert a couple of drivers to use the new
	  devm_regulator_bulk_get_enable().
	- Squash all IIO patches into one.

Patch 1:
	Add new devm-helper APIs to docs.
Patch 2:
	simplified CLK driver(s)
Patch 3:
	simplified GPU driver(s)
Patch 4 - 5:
	simplified hwmon driver(s)
Patch 6 - 14:
	simplified IIO driver(s)

README 

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.
