Instead of explicitly using PWM_SIFIVE_PWMCMP0 + pwm->hwpwm * PWM_SIFIVE_SIZE_PWMCMP for each access to one of the PWMCMP registers, introduce a macro that takes the hwpwm id as parameter. For the register definition using a plain 4 instead of the cpp constant PWM_SIFIVE_SIZE_PWMCMP is easier to read, so define the offset macro without the constant. The latter can then be dropped as there are no users left.

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.
