runtime_pm.rst still says

  * If the resume callback returns an error code, the PM core regards this as a
    fatal error and will refuse to run the helper functions described in Section
    4 for the device, until its status is directly set to either 'active', or
    'suspended' (by means of special helper functions provided by the PM core
    for this purpose).

which needs an update now?
