    rtc: lpc32xx: remove irq > NR_IRQS check from probe() · 529af7d1
    Vladimir Zapolskiy authored
    If the driver is used on an ARM platform with SPARSE_IRQ defined,
    semantics of NR_IRQS is different (minimal value of virtual irqs)
    and by default it is set to 16, see arch/arm/include/asm/irq.h.
    This value may be less than the actual number of virtual irqs, which
    may break the driver initialization. The check removal allows to use
    the driver on such a platform, and, if irq controller driver works
    correctly, the check is not needed on legacy platforms.
    Fixes a runtime problem:
