[Test]
This is requested and tested by AMD as described in LP:1944382
[Where problems could occur]
Low risk. This only affects devices of AMD's Yellow Carp.
== original descriptions ==
Like all XHCI controllers yellow carp XHCI by default will not use runtime PM
and needs to be added to an allow list. AMD has validated that XHCI runtime PM
is safe.
