Additionally, most of its usage in DPMS sequences\nis for stream->sink->link, which can be replaced with stream->link,\nas the two should always be the same.\n\n[How]\n* Replace stream->sink->link in DPMS on/off\n* Add assert to USB4 BW allocation where sink is required\n* Avoid inconsistencies in resource access, e.g. don't repeat\nstream->link after it was already saved to a local variable\n* Pull out effective VPG calculation to helper getter\n* Formatting fixes","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0b1eebd359685dd681f6e0df5540a5bb985a27bf","tags":[]},{"url":"https://git.kernel.org/stable/c/8fa813b7fd1eccbed13e126166cf764f1f11a7d3","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
