Description Brent Fulgham 2020-12-16 11:15:02 PST 
We are extending a dynamic IOKit class extension to AppleAVDUserClient, but this is not being consistently consumed on some platforms. While this bug is investigated, temporarily add a rule to allow access without the dynamic extension.

This change might not be needed, since I am not sure there is any difference in behavior between if and when.
