The place where this register writel() that masks one interrupt is placed does not guarantee that the device is powered so that's not allowed. Moreover imx8mq_mipi_csi_start_stream() masks the interrupt anyway so the write is not even needed. Remove it as this is a mistake that slipped in with the driver.
