Commit 935df1bd40d43c4ee91838c42a20e9af751885cc has removed an assignment statement for 'out_irq->np' right after label 'skiplevel', causing the new parent acquired from function of_irq_find_parent didn't being stored to 'out_irq->np' as it supposed to. Under some conditions this can resuit in multiple corruptions and leakages to device nodes. Update 'out_irq->np' before jumping to label 'skiplevel'.
