Technically it fixes a real problem, but realistically there is no real need to backport these patches because of other suspend-resume troubles that also existed all the time and haven't been resolved yet (likely fixes won't be backportable). In general suspend-resume kinda works and fails mostly under some load (like stress testing), at least that's the case for T30.
