leds: leds-mc13783: Remove duplicate field in platform data
LED platform data are overwhelmed by excessive field "max_cur" which just replicates few bits of "led_control" field. This patch removes this field and adds a definition for the current settings in the header. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Bryan Wu <cooloney@gmail.com>
