It may happen, for example when querying a PHB interrupt # while the PHB is in an error state. # # In that case, we should consider the interrupt to be invalid when # checking its state in the irq_get_irqchip_state() handler. # # Fixes: da15c03b047d ("powerpc/xive: Implement get_irqchip_state method for XIVE to fix shutdown race") # Cc: stable@vger.kernel.org # v5.4+ # Signed-off-by:
