leds-lp55xx: use common lp55xx data structure in _probe()
LP5521 and LP5523 data structures have common features. Use common lp55xx data structures rather than chip specific data. Legacy code in probe is replaced with this new data structures. lp55xx_chip : Common data between lp5521_chip and lp5523_chip lp55xx_led : Common LED structure between lp5521_led and lp5523_led lp55xx_platform_data : Common platform data between lp5521_platform_data and lp5523_platform_data Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
