Ville Syrjälä fd7a9d8fa1 drm/i915: Fix g4x fbc watermark enable
'level' here means the highest level we can't use, so when checking
the fbc watermarks we need a -1 to get at the last enabled level.

While at if refactor the code a bit to declutter
g4x_compute_pipe_wm().

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.
