heminhong ef32c3cc9c drm/i915: correct the input parameter on _intel_dsb_commit()
Current, the dewake_scanline variable is defined as unsigned int,
an unsigned int variable that is always greater than or equal to 0.
when _intel_dsb_commit function is called by intel_dsb_commit function,
the dewake_scanline variable may have an int value.
So the dewake_scanline variable is necessary to defined as an int.

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.
