The header doesn't make use of any symbols declared in <linux/pwm.h>. There are tree files that #include <mfd/lp3943.h>. Two of them (i.e. drivers/gpio/gpio-lp3943.c and drivers/mfd/lp3943.c) also don't use any and the third (drivers/pwm/pwm-lp3943.c) has an explicit include of <linux/pwm.h> itself. So drop the unused include. The intended side effect is that drivers/gpio/gpio-lp3943.c and drivers/mfd/lp3943.c stop importing the "PWM" module namespace.

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.
