Well this was a mess to figure out.
The only fix I can figure out here is to remove the
depends on LEDS_CLASS_MULTI_COLOR || !LEDS_CLASS_MULTI_COLOR
from each child device and add
select LEDS_CLASS_MULTI_COLOR
to the LP55XX_COMMON
This way the Multi color framework will inherit the symbol that was
set by the COMMON flag which is inherited by majority from the
child flags.
Did you try this?

Yes I did
That gave unmet dependencies.

When I was testing that yesterday I also had the same warning at some
point of testing different Kconfig setups, but with what I showed above
it ceased to appear. Now every time I am doing "make oldconfig" the
CONFIG_LEDS_LP55XX_COMMON=y entry gets changed to =m with the config
from the test bot.
That is not what I saw in my testing especially after doing a distclean
Could you please give your exact steps after "make distclean" and
copying test bot config to the kernel root directory?
Also, please share the toolchain you're using for tests.
