In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Remove sink usage from DPMS [Why] stream->sink is optional and can be null, so should always be checked before dereference. Additionally, most of its usage in DPMS sequences is for stream->sink->link, which can be replaced with stream->link, as the two should always be the same. [How] * Replace stream->sink->link in DPMS on/off * Add assert to USB4 BW allocation where sink is required * Avoid inconsistencies in resource access, e.g. don't repeat stream->link after it was already saved to a local variable * Pull out effective VPG calculation to helper getter * Formatting fixes
