[ Upstream commit 0435bcc4e5858c632c1b6d5afa637580d9779890 ]
The init callback must not decrement the reference count of the provided irqchip OF node.
This should not cause any trouble currently, but if the driver ever starts probe deferring it could lead to warnings about reference underflow and saturation.
