1108  irq_settings_clr_and_set(desc, clr, set)
1110  trigger等于irqd_get_trigger_type( & irq_data)
1112  清除中断标志
1114  如果irq_settings_has_no_balance_set(desc)则设置中断标志
1116  如果irq_settings_is_per_cpu(desc)则设置中断标志
1118  如果irq_settings_can_move_pcntxt(desc)则设置中断标志
1120  如果irq_settings_is_level(desc)则设置中断标志
1123  tmp等于取中断触发方式
1124  如果tmp不等于IRQ_TYPE_NONE则trigger等于tmp
1127  设置中断标志
1129  irq_put_desc_unlock(desc, flags)
