The variable pval is only used in a single block in the function sun4i_pwm_calculate(). So declare it in a more local scope to simplify the function for humans and compilers. While at it also simplify assignment to pval. While the diffstat for this patch is negative for this patch I still thing the advantage of having a narrower scope is beneficial. In my compiler / .config setup (gcc 8.2.1, arm/imx_v6_v7_defconfig + COMPILE_TEST + PWM_SUN4I) this change doesn't result in any binary changes.

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.
