In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/hdmi: Fix breakage at probing nvhdmi-mcp driver After restructuring and splitting the HDMI codec driver code, each HDMI codec driver contains the own build_controls and build_pcms ops. A copy-n-paste error put the wrong entries for nvhdmi-mcp driver; both build_controls and build_pcms are swapped. Unfortunately both callbacks have the very same form, and the compiler didn't complain it, either. This resulted in a NULL dereference because the PCM instance hasn't been initialized at calling the build_controls callback. Fix it by passing the proper entries.
