    x86/irq: Move IS_ERR_OR_NULL() check into common do_IRQ() code · d6f83427
    Heiner Kallweit authored Aug 19, 2019
    
    
    Both the 64bit and the 32bit handle_irq() implementation check the irq
    descriptor pointer with IS_ERR_OR_NULL() and return failure. That can be
    done simpler in the common do_IRQ() code.
    
    This reduces the 64bit handle_irq() function to a wrapper around
    generic_handle_irq_desc(). Invoke it directly from do_IRQ() to spare the
    extra function call.
    
    [ tglx: Got rid of the #ifdef and massaged changelog ]
