Chaitanya Kumar Borah 6f1e094fb6 drm/i915/color: Preserve sign bit when int_bits is Zero
When int_bits == 0, we lose the sign bit when we do the range check
and apply the mask.

Fix this by ensuring a minimum of one integer bit, which guarantees space
for the sign bit in fully fractional representations (e.g. S0.12)

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.
