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?
