找不到设备节点


[root@ATK-stm32mp1]:/lib/modules/5.4.31$ modprobe dtsled.ko
[   74.086367] dtsled: module verification failed: signature and/or required key missing - tainting kernel
[   74.095086] stm32mp1_led node nost find!
[   74.218989] stm32mp1_led node nost find!
modprobe: can't load module dtsled.ko (dtsled.ko): Invalid argument
[root@ATK-stm32mp1]:/lib/modules/5.4.31$ ./dtsledApp /dev/dtsled 1

能帮我分析下吗

stm32mp157d-atk.dts加入节点stm32mp1_led时  写成stm32mp1-led

导致找不到节点
