2012-06-18usb: tegra: otg: fix unbalanced suspend/resumeXin Xie
Becasue of a previous workaround, suspend/resume pair is implemented as suspend/complete pair in the driver's dev_pm_ops field. If any driver suspend routine (which is called before otg suspend) failed, then tegra_otg_resume() will be called even tegra_otg_suspend() is not called. This will cause disable the OTG clock, and OTG will not generate any more IRQ. Ideal fix would be use suspend/resume pair to implement the dev_pm_ops, but this might break previous workaround. This patch check suspend() routine is called or not in the resume routine; even we use suspend/ resume pair in the future, it will not cause bad behaviour.
