[203760.710640] sysfs: cannot create duplicate filename '/devices/virtual/100ask_led_class'
by brianyi from LinuxQuestions.org on (#6PGRC)
could sb help me, I'm learning linux driver programming, because of my fault operation, I didn't call class_destroy(). So, next time I insmod into kernel, then kernel message shows "sysfs: cannot create duplicate filename '/devices/virtual/100ask_led_class'" , and I find that file `/sys/devices/virtual/100ask_led_class` exist, what should I do if I forget class_destroy()?
