The rockchip DRM driver is quite careful to disable interrupts when taking a lock that is also taken in interrupt context, which is a good thing. What is a bit over the top is to use spin_lock_irqsave when already in interrupt context, as you cannot take another interrupt again, and disabling interrupt is just pure overhead. Switching to the non _irqsave version in interrupt context is more logical, and less heavy handed.
