leds: el15203000: Introduce to_el15203000_led() helper
Introduce a helper to replace open coded container_of() calls. At the same time move ldev member to be first in the struct el15203000_led, that makes container_of() effectivelly a no-op. Signed-off-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Pavel Machek <pavel@ucw.cz>
