Your changelog is incorrect. If you had checked the history, you would
have learned that the function was added without callers in the first
place and never gained any callers since then.
How about first checking what the Host2CA AV/C command is for, and then
deciding on whether to add proper usage of it or to drop its implementation
from the source for good.
