No, device's drvdata belongs to _this_ driver, and it is supposed to
manage it and use as it sees fit.

Note platform_set_drvdata(pdev, info) later in this function along with
platform_set_drvdata(pdev, NULL) in twl4030_vibra_remove(), which means
that with your change you will be able to bind the device only once.
