test for "spurious" IRQ ignores possible IRQ_WAKE_THREAD value

["Robert P. J. Day" <rpjday@crashcourse.ca>]

  never ashamed to embarrass myself in public, i just noticed the
following.  from kernel/irq/spurious.c:

...
static void
__report_bad_irq(unsigned int irq, struct irq_desc *desc,
                 irqreturn_t action_ret)
{
        struct irqaction *action;

        if (action_ret != IRQ_HANDLED && action_ret != IRQ_NONE) {
                printk(KERN_ERR "irq event %d: bogus return value %x\n",
                                irq, action_ret);

  but from include/linux/irqreturn.h, we see *three* possible return
values:

enum irqreturn {
        IRQ_NONE,
        IRQ_HANDLED,
        IRQ_WAKE_THREAD,
};

typedef enum irqreturn irqreturn_t;
#define IRQ_RETVAL(x)   ((x) != IRQ_NONE)

  is there an inconsistency here?
