Subject: leds/leds-s3c24xx: use devm_gpio_request
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5ecf6e40bbb8649b8418c8038a2af1faefbc56e4;p=linux-beck.git

leds/leds-s3c24xx: use devm_gpio_request

why?
because if the led_classdev_register fails we wont do gpio free
because using devm_ functions, there is no need for error paths
