This may not be needed, if you use the rgblight "get" functions. https://docs.qmk.fm/#/feature_rgblight?id=query

This block isn't needed. ```suggestion ```

this was removed on the master, now in this branch this `#ifndef` has no `#endif`

The backslashes at the end of these lines are not necessary. You can keep them if you want as it isn't hurting anything, but IMO it looks neater without them.

```suggestion ``` QMK calculates this on its own, now.

```suggestion #define L_LOWER (1 << 1) ```

```suggestion #define L_RAISE (1 << 2) ```

```suggestion #define L_ADJUST_TRI (L_ADJUST | L_RAISE | L_LOWER) ```

```suggestion #define L_ADJUST (1 << 16) ```

The stuff from the serial_config.h file should be moved into this file, and that file removed.
