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.
