[PATCH v1 04/10] PM: runtime: Drop status check from pm_runtime_force_resume()

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Since pm_runtime_force_resume() requires pm_runtime_force_suspend() to
be called before it on the same device, the runtime PM status of that
device is RPM_SUSPENDED when it is called unless the device's runtime
PM status is changed somewhere else in the meantime.

However, even if that happens, the power.needs_force_resume
check is still required to pass and that flag is only set by
pm_runtime_force_suspend() and it is cleared at the end of
pm_runtime_force_resume(), so it cannot be taken into account
twice in a row.

Accordingly, the pm_runtime_status_suspended(dev) check in
pm_runtime_force_resume() is redundant, so drop it.
