* Use White channel on RGBW LEDs Co-authored-by: kwerdenker <sebastian.spindler@gmail.com> * Manually apply white channel to array * Move where convert_rgb_to_rgbw is called * Fix type for rgbw led struct * Add changes to Ergodox EZ can revert if deemed necessary * Revert "Add changes to Ergodox EZ" This reverts commit aa44db198d40d758ca10470eb94615513592d1dd. * Revert "Fix type for rgbw led struct" This reverts commit c5c744cba040201cc0d124400773cf13f8a2cf22. * Revert "Move where convert_rgb_to_rgbw is called" This reverts commit cd7f17caf6dd30731c54b3be54490fe4519444f9. * Revert changes and fix up functions * Enable white channel for Ergodox EZ as well * Only run conversion of rgblight is enabled Co-authored-by: kwerdenker <sebastian.spindler@gmail.com>
