Linux kernel source tree
820e04cb8c
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: There are devices where the iDisp HDA codec for HDMI is disconnected and it is not present on the HDA bus. This usually happens on systems with dGPU, but not limited to them. How SOF tried to deal with this is to drop in a dummy codec in place of the iDisp to allow the topology to be loaded, but these PCM devices are unusable, they fail when user tries to use them. PA/PW is probing the PCM devices on probe and that causes the kernel log to fill up with errors, which is harmless but disturbing. This series will use the filter function to prevent the creation of the HDMI PCM devices in the first place (like HDA legacy stack will not present HDMI devices if the codec is not visible). The topology still loads, we still use dummy codec to satisfy it, but there will be no dummy PCM devices created. The first two patch handles the same issue that was discovered by the ignored link: a NULL dereference. I'm not sure if both is needed, but I felt that fixing it in one place and leaving the other open might not be future proof. If I would to pick one, I would likely go with the patch for the soc-core. |

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.
