函数名称：opal_reverttper

函数原型：static int opal_reverttper(struct opal_dev *dev, struct opal_key *opal, bool psid)

返回类型：int

参数：

类型参数名称
struct opal_dev *dev
struct opal_key *opal
boolpsid
2333  const struct opal_step revert_steps[] = {{start_SIDASP_opal_session, opal}, {revert_tper, }}
2337  const struct opal_step psid_revert_steps[] = {{start_PSID_opal_session, opal}, {revert_tper, }}
2344  mutex_lock( & dev_lock)
2345  setup_opal_dev(dev)
2346  如果psid则ret等于execute_steps(dev, psid_revert_steps, ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(psid_revert_steps))
2349  否则ret等于execute_steps(dev, revert_steps, ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(revert_steps))
2352  mutex_unlock - release the mutex*@lock: the mutex to be released* Unlock a mutex that has been locked by this task previously.* This function must not be used in interrupt context. Unlocking* of a not locked mutex is not allowed.
2358  如果非ret则clean_opal_dev(dev)
2361  返回:ret
