The intention was to check whether the primary plane is enabled without any sprites planes being enabled. Instead we ended up checking whether just any one of the planes is enabled. g4x isn't vlv/chv and cxsr only works with the primary plane. Fix the check to examine the bitmask of active planes rather than the number of bits set in said bitmask.

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.
