[media] davinci: vpif: add check for genuine interrupts in the isr
As the same interrupt is shared between capture and display devices, sometimes we get isr calls where the interrupt might not genuinely belong to capture or display. Hence, add a condition in the isr to check for interrupt ownership and channel number to make sure we do not service wrong interrupts.
