kstrdup_const() and kfree_const() can be confusing in code built as a
module. In such a case, it does not do what one could expect from the name
of the functions.
The code is not wrong by itself, but in such a case, it is equivalent to
kstrdup() and kfree().
So, keep thinks simple and straightforward.
This reverts commit 379b63e7e6 ("drm/i915/display: Save a few bytes of
memory in intel_backlight_device_register()")

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.
