leds-lm3530: Fix smatch warnings
Fixes the following smatch warnings:
drivers/leds/leds-lm3530.c:361 lm3530_mode_set() info:
why not propagate 'mode' from lm3530_get_mode_from_str() instead of -22?
drivers/leds/leds-lm3530.c:432 lm3530_probe() info:
why not propagate 'err' from lm3530_init_registers() instead of -19?
drivers/leds/leds-lm3530.c:438 lm3530_probe() info:
why not propagate 'err' from led_classdev_register() instead of -19?
