[ Upstream commit c111566bea7ccd8a05e2c56f1fb3cbb6f4b7b441 ] pm_runtime_get_if_in_use() bumps up the PM-runtime usage count if it is not equal to zero and the device's PM-runtime status is 'active'. This works for drivers that do not use autoidle, but for those that do, the function returns zero even when the device is active. In order to maintain sane device state while the device is powered on in the hope that it'll be needed, pm_runtime_get_if_active(dev, true) returns a positive value if the device's PM-runtime status is 'active' when it is called, in which case it also increments the device's usage count. If the second argument of pm_runtime_get_if_active() is 'false', the function behaves just like pm_runtime_get_if_in_use(), so redefine the latter as a wrapper around the former.
