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.
