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 ?
