Uwe Kleine-König ca478d8a4b pwm: pca9685: Don't disable hardware in .free()
It's the responsibility of the consumer to disable the hardware before
it's released. And there are use cases where it's beneficial to keep the
PWM on, e.g. to keep a backlight on before kexec()ing into a new kernel.

Even if it would be considered right to disable on pwm_put(), this
should be done in the core and not each individual driver. So drop the
hardware access in .free().

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 reStructuredText 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.
