PM: QoS: Add CPU latency QoS API wrappers (fa048c59) · Commits · 戴 / test

Introduce (temporary) wrappers around pm_qos_request(), pm_qos_request_active() and pm_qos_add/update/remove_request() to provide replacements for them with function signatures that will be used in the final CPU latency QoS API, so that the users of it can be switched over to the new arrangement one by one before the API is finally set. No intentional functional impact. Signed-off-by:
