PM: PM QOS update fix (25f3a5a2) · Commits · 戴 / test

This update handles a use case where pm_qos update requests need to silently fail if the update is being sent to a handle that is NULL. The problem was that the original pm_qos silently fails when a request update is passed to a parameter that has not been added to the list yet. This update restores that behavior. Signed-off-by:
