error: Unknown symbol leds_list
I wanted to use led-class function in led driver (/linux-2.6.20/drivers/leds/led-class.c) as a module.
I am working on Kernel 2.6.20.
I wanted to insert this module on Fresscale Board.
I Compiled this as a module using LTIB utility, given with Board.
At the time of kernel configuration, I chose LED Class Support as a Module.
It complied successfully, & gave me led-class.ko file.
I copy this file on Board & Try to insert it using insmod
$insmod led-class.ko (It generate the following error)
"led_class: Unknown symbol leds_list
insmod: cannot insert `led-class.ko': Unknown symbol in module (-1): No such file or directory"
What is the meaning of this. Plz help me.
Thank you In Advance.
