I've now tested v16 with my SuperH Mobile platform device Runtime PM
implementation. All seems fine and my patches for patches for drivers
such as i2c master, fbdev, v4l2 and uio behave as expected.

Acked-by: Magnus Damm <damm@...l.co.jp>

The patch "PM: Runtime PM v15 - Platform Device Bus Support" works
well with v16 and does not need any update.

Cheers,
