Arguably, a function called "reset" should put the backlight level and color in a known state.

But what do bonw14, darp5, and oryp5 actually need to do for I2C when waking the CPU? Does kbled_reset need to be called at all?

In my tinkering this appeares to break the system76-acpi-dkms module, making the LEDs unusable with the hardware controls inside Linux. If you remove the module they begin to work again.

I may have spoken too soon... if I was wrong, I'll post about it again here...but seems my distro is not using the master branch.

So it does not appear to be this commit, however the current master does seem to break things with the keyboard backlight controls when the acpi module is in use.
