From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx> The 4th argument of ravb_setup_irq() is used to save the IRQ number that will be further used by the driver code. Not all ravb_setup_irqs() calls need to save the IRQ number. The previous code used to pass a dummy variable as the 4th argument in case the IRQ is not needed for further usage. That is not necessary as the code from ravb_setup_irq() can detect by itself if the IRQ needs to be saved. Thus, get rid of the code that is not needed.
