ebus is being NULL checked however it is being dereferenced earlier on the assignment bus = ebus_to_hbus(ebus). Fix this by moving the assignment to after the NULL check on ebus to avoid a NULL pointer dereference error.
ebus_to_hbus() doesn't dereference "ebus" it just uses it for pointer math.
#define ebus_to_hbus(ebus) (&(ebus)->bus)
If you pass a NULL to there, it returns an offset starting from NULL but it doesn't Oops.
