Bluetooth: btusb: wake system up when receives a wake irq
Browse files Browse the repository at this point in the history
Currrently we are disabling this wake irq after receiving it. If this
happens before we finish suspend and the pm event check is disabled,
the system will continue suspending, and this irq would not work again.

We may need to abort system suspend to avoid that.
