Not true, there is an #else further down.
That said, this code is clearly a bit confusing.
It would be better if at the beginning of the function we'd have this:
#if !IS_REACHABLE(CONFIG_RC_CORE)
caps &= ~CEC_CAP_RC;
#endif
and then drop the #else bit and (as you do in this patch) move the #if up.
Can you make a new patch for this?
Thanks!
