Looking at the code I'm a little concerned to see the direction this is
going. There was originally a reason that there were two options, it was
related to being able to compile as much of the LED code as a module as
possible.

It looks like commit 5ada28bf76752e33dce3d807bf0dfbe6d1b943ad changed
the tristate to a bool at which point the separate option obviously
becomes pointless.

Rather than accept the current direction and force everything builtin,
I'd much rather this code became modular capable again. There is no good
reason we should be forced to build everything into a kernel.

Cheers,

Richard
