原因是在内核配置中没有添加相关LED的配置

在内核目录下配置

#make menuconfig

Symbol: LEDS_CLASS [=m]

│ Prompt: LED Class Support

│ Defined at drivers/leds/Kconfig:12

│ Depends on: NEW_LEDS [=y]

│ Location: 

│ -> Device Drivers

│ -> LED Support (NEW_LEDS [=y])

│ Selected by: ADB_PMU_LED [=n] && MACINTOSH_DRIVERS [=n] && ADB_PMU [=n] || IWLWIFI [=n] && NETDEVICES [=y] && WLAN [=y] && PCI [=n] && MAC80211 [=y] && WLAN_ │

然后重新make一下，将uImage下载到开发板，重新加载驱动就可以了。。。
