[Bug] SPLIT_HAPTIC_ENABLE doesn't work

[Onefabis]

Describe the Bug

I did a test with your PR.
#define SPLIT_HAPTIC_ENABLE still don't want to work on the slave side, only on the master side. If I switch the sides connection, the problem remains the same: master vibrating, slave - not.

Sorry, I've finally been able to test this. Unfortunately, it seems like this works fine for me, no matter which side is plugged in, or if only one side has the haptics connected.

Can confirm as well that this works for me as well
