With devm_clk_get_prepared() the call to clk_unprepare() can be dropped from the error path and the remove callback. With devm_pwmchip_add() pwmchip_remove() can be dropped. Then the remove callback is empty and can go away, too. With vt8500_pwm_remove() the last user of platform_get_drvdata() is gone and so platform_set_drvdata() can be dropped, too. Also use dev_err_probe() for simplified (and improved) error reporting.

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.
