Update the LinuxLEDController to support multicolor LEDs defined by the Linux kernel. For multicolor LEDs Linux exposes a single brightness which allows a range of 0 (off) to 255 (max) and a multi_intensity value that accepts multiple channels of colors. This current implementation assumes that there are 3 multi_intensity channels between 0 and 255. https://docs.kernel.org/leds/leds-class-multicolor.html Note that for now in Linux the brightness value doesn't so much affect the brightness of the LED as it does apply a coefficient to the individual channel intensities. For now hard code the brightness to 255 and simply adjust the intensities to alter the color. This change should keep the existing sysfs code path as-is and only attempt to use this new method when a led_rgb_path is present in the config file. For reference, my OpenRGB.json has the following lines: ` "LinuxLEDDevices" : { "devices": [ { "name": "Fan LED 1", "rgb_path": "/sys/class/leds/rgb:programming-0/" } ] }` Signed-off-by: Chris Morgan <macromorgan@hotmail.com>
