BTW yes I repro the problem.
Checked the makefile and led-core.c is compiled with NEW_LEDS and
led-class is compiled with LEDS_CLASS.
led_init_default_state_get is in led-core.c and this is the problem with
using LEDS_CLASS instead of NEW_LEDS...
But actually why we are putting led_init_default_state_get behind a
config? IMHO we should compile it anyway.
So my suggestion is to keep the LEDS_CLASS and just remove the part for
led_init_default_state_get.
Also why IS_ENABLED instead of a simple ifdef? (in leds.h there is a mix
of both so I wonder if we should use one or the other)
