    clocksource/drivers/rockchip: Fix bad NO_IRQ usage · ccc42592
    Daniel Lezcano authored
    The current code assumes the 'irq_of_parse_and_map' will return NO_IRQ in case
    of failure. Unfortunately, the NO_IRQ is not consistent across the different
    architectures and we must not rely on it.
    
    NO_IRQ is equal to '-1' on ARM and 'irq_of_parse_and_map' returns '0' in case
    of an error. Hence, the latter won't be detected and will lead to a crash.
    
    Fix this by just checking 'irq' is different from zero.
