  * Description:
- *    Update the queue's runtime status according to the return value of the
- *    device's runtime_resume function. If the resume was successful, call
- *    blk_set_runtime_active() to do the real work of restarting the queue.
+ *    For historical reasons, this routine merely calls blk_set_runtime_active()
+ *    to do the real work of restarting the queue.  It does this regardless of
+ *    whether the device's runtime-resume succeeded; even if it failed the
+ *    driver or error handler will need to communicate with the device.
  *
  *    This function should be called near the end of the device's
  *    runtime_resume callback.
