Compared to direct calls to pwmchip_get_drvdata() a dedicated function has two upsides: A better name and the right type. So the code becomes easier to read and the new function is harder to use wrongly. Another side effect (which is the secret motivation for this patch, but shhh) is that the driver becomes a bit easier to backport to kernel versions that don't have devm_pwmchip_alloc() yet.

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.
