The current implementation of change_lut_val_precision() is just a convoluted way of shifting by 8. Implement the proper rounding by just using drm_color_lut_extract() and intel_color_lut_pack() like everyone else does. And as the uapi can't handle >=1.0 values but the hardware can we need to clamp the results appropriately in the readout path.

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.
