When helix/rev2 was using split_common, it didn't work properly and I couldn't type on the right hand side. The cause is that the following code, added in 0.16.0 to `quantum/keyboard.c`, does not include `quantum/split_common/split_util.h` but instead includes `keyboards/helix/rev2/split_util.h`. Therefore, `split_pre_init()/split_post_init()` in `quantum/split_common/split_util.c` was not called. ```c #ifdef SPLIT_KEYBOARD # include "split_util.h" #endif ```
