Thomas Zimmermann 192cc9f2b7 drm/ast: Add empty initializer for VBIOS modes
VBIOS mode tables are terminated by an entry with a refresh rate of
0xff. The code is hard to read and fragile to use. Therefore create
an empty entry with AST_VBIOS_MODE_INVALID to terminate each mode list.

Stop at the invalid entry when searching for modes in the tables.
Instead of testing for refresh == 0xff, test with a helper function if
the mode's size and refresh have meaningful values.

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.
