Since platform_get_irq() never returned zero, so it need not to check whether it returned zero, and we use the return error code of platform_get_irq() to replace the current return error code. Please refer to the commit a85a6c86c25b ("driver core: platform: Clarify that IRQ 0 is invalid") to get that platform_get_irq() never returned zero.
