i was going through the code leds-gpio.c. i found a function "platform_gpio_blink_set" declared under private data of "gpio_led_data",and was trying to get through this function. But hardly i can find any link to definition for the same anywhere.

Hi,

That is a function pointer, so you should search assignments to that pointer. That way you can find the real function you are looking for.

I've spotted such usages in a lot of places, outside the kernel as well. Just wanted know if there is a smarted way of finding the assignments, like some tools or any other tips which people could use to make life easier ?

I've been able to print the address of the functions (once it has been assigned), then check the System.map for the function name.

Thank you all for the smart answers!
