    media: ipu3-cio2: Request IRQ earlier
    
    [ Upstream commit a069f79bfa6ec1ea0744981ea8425c8a25322579 ]
    
    Call devm_request_irq() before registering the async notifier, as otherwise
    it would be possible to use the device before the interrupts could be
    delivered to the driver.
