I think that you need to add test case.

Bug title is different from this.

It would be good to add explanation for this patch.

Do not touch unrelated line.

I don't see why r164266 was influenced on vibration feature.

[CoordinatedGraphics][EFL] Remove view_source functions.

Add a new line.

Why should we call stopVibration() when m_isVibrating is false ?

You should not return here after canceling vibration. If a new vibration pattern is set, then existing vibration is canceled and the new vibration should work.

Yes, I will add a checking statement before calling stopVibration().

Spec. describes the algorithm for vibrate() method, so it would be better to follow the sequences.
