Subject: leds: tlc591xx: use devm_led_classdev_register_ext()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5b4b723c483f5027da77409f34b8b4602ee1e557;p=linux.git

leds: tlc591xx: use devm_led_classdev_register_ext()

Use devm_led_classdev_register_ext() to pass the fwnode to the LED core.
The fwnode can then be used by the firmware core to create meaningful
names.
