Uwe Kleine-König dd47a83453 leds: pwm: convert to atomic PWM API
pwm_config(), pwm_enable() and pwm_disable() should get removed in the
long run. So update the driver to use the atomic API that is here to
stay.

A few side effects:

 - led_pwm_set() now returns an error when setting the PWM fails.
 - During .probe() the PWM isn't disabled implicitly by pwm_apply_args()
   any more.

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.
