commit7073c7fc8dupstream. Actually check the return value from pll_ops->init_pll() as it can return an error. If the card's BIOS didn't run because it's not the primary VGA card the fact that the xclk source is unsupported is printed as shown below but the driver continues on regardless and on my machine causes a hard lock up.

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.
