Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ALSA: hda/hdmi: Fix breakage at probing nvhdmi-mcp driver<br />
<br />
After restructuring and splitting the HDMI codec driver code, each<br />
HDMI codec driver contains the own build_controls and build_pcms ops.<br />
A copy-n-paste error put the wrong entries for nvhdmi-mcp driver; both<br />
build_controls and build_pcms are swapped. Unfortunately both<br />
callbacks have the very same form, and the compiler didn&#39;t complain<br />
it, either. This resulted in a NULL dereference because the PCM<br />
instance hasn&#39;t been initialized at calling the build_controls<br />
callback.<br />
<br />
Fix it by passing the proper entries.
