android 深度睡眠出现的问题

问题描述：
前提进入是深睡眠模式，按唤醒键1秒钟左右正常唤醒，如果快速按不能点亮屏（也就是LCD驱动的resume没有执行）。

上面打印信息，经过很多次的抓取都是wakeup wake lock不一样的。

从上面可以看出，唤醒键按长按1秒钟左右（正常唤醒），和不正常按键（快速按唤醒键），不同地方上面有一个唤醒锁
wakeup wake lock: mmc_delayed_work  和wakeup wake lock: event2-992不一样。为什么会这样呢。
找不方向，请指点方向。 --------------------编程问答-------------------- 关注学习中！
up --------------------编程问答-------------------- 跟踪代码发现：
kernel/power/main.c
   static ssize_t state_store(struct kobject *kobj, struct kobj_attribute *attr,const char *buf, size_t n)
函数没有调用（快速按键的时候）。

我不明白没有进入tate_store()函数。但是为什么suspend能进入呢。

state_store(),是上层传下来参数(buf).没有传下来，我怎么执行呢。
