Thomas Zimmermann ad09bb7cbd drm/simpledrm: Do not upcast in release helpers 
[ Upstream commit d231cde7c8 ]

The res pointer passed to simpledrm_device_release_clocks() and
simpledrm_device_release_regulators() points to an instance of
struct simpledrm_device. No need to upcast from struct drm_device.
The upcast is harmless, as DRM device is the first field in struct
simpledrm_device.

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.
