I need to NACK this one sorry, if only because I added the RGB control 
in hid-asus-ally as a per-LED control and it works very well. You'll see 
it once I submit that series upstream again.

The distinction between MCU mode and Software mode for RGB is frankly a 
pain in the arse. For Ally we will want software mode (per-led) as that 
allows just one USB write for all LEDs, and no need to do a set/apply to 
make the LEDs change. The benefit being that the LEDs can change rapidly 
and there will be no "blink".

I'll write more on patch 10

Cheers,
Luke.
