Read the HDMI infoframes from the hbuf and unpack them into the crtc state. Well, actually just AVI infoframe for now but let's write the infoframe readout code in a more generic fashion in case we expand this later. Note that Daniel was sceptical about the benefit if this and also concerned about the potential for crappy sdvo encoders not implementing the hbuf read commands. My (admittedly limited) experience is that such encoders don't implement even the get/set hdmi encoding commands and thus would always be treated as dvi only. Hence I believe this is safe, and also IMO preferable having quirks to deal with missing readout support. The readout support is neatly isolated in the sdvo code whereas the quirk would leak to other parts of the driver (state checker, fastboot, etc.) thus complicating the lives of other people.

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.
