------------------ From: hongkun.cao <[email protected]> commit 5edf673d07fdcb6498be24914f3f38f8d8843199 upstream. When a dual-edge irq is triggered, an incorrect irq will be reported on condition that the external signal is not stable and this incorrect irq has been registered. Correct the register offset.
