Bingbu Cao 09f20f2bca media: intel-ipu3: cio2: Handle IRQs until INT_STS is cleared ... Interrupt behavior shows that some time the frame end and frame start of next frame is unstable and can range from several to hundreds of micro-sec. In the case of ~10us, isr may not clear next sof interrupt status in single handling, which prevents new interrupts from coming. Fix this by handling all pending IRQs before exiting isr, so any abnormal behavior results from very short interrupt status changes is protected.
