[PATCH] leds: gpio: set led_dat->gpiod pointer for OF defined GPIO leds

From: Liviu Dudau
Date: Wed Oct 17 2018 - 20:14:42 EST

Commit 45d4c6de4e49 ("leds: gpio: Try to lookup gpiod from device")
removed the common code path that set the led_dat->gpiod pointer in
create_gpio_led(), but only added it back for the devices that have
a valid gpio_led_platform_data structure. Calling gpio_leds_create()
in gpio_led_probe() is not enough to get a valid gpiod pointer.

Fortunately enough, gpio_leds_create() already gets the needed pointer,
we just need to assign it to the relevant gpio_led_data structure.

I found this issue while testing linux-next-20181017, I don't know how
stable the leds for-next tree is in terms of commit IDs, if that gets
rebased then the Fixes commit ID needs updating.

Best regards,
