Public bug reported:
[Impact]
* The Ubuntu RISC-V kernel carries out-of-tree patches to enable
the two LEDs on the SiFive Unmatched board.
* There is now an upstream solution to enable the LEDs that appears
a little different from userspace. With the out-of-tree patches the
three colours in the RGB LED appears as 3 different LEDs, but upstream
models them as 1 RGB LED.
* Replacing the out-of-tree patches with the upstream solution will
make Ubuntu kernels behave like the upstream kernel going forward.
[Test Plan]
* Boot Ubuntu on the Unmatched board and look at how the LEDs show up
in /sys/class/leds
* Check that both the green D12 and all three colours of D2 can still
be controlled from userspace.
[Where problems could occur]
* Users may have scripts setting up LEDs that will no longer work when
updating to Kinetic with this change.
