Nicely found!
The cec_delete_adapter() function calls __cec_s_phys_addr(CEC_PHYS_ADDR_INVALID)
which would normally call adap_enable(false), except when the device node was
already unregistered, in which case it just returns immediately.
The patch below should fix this. Let me know if it works, and I'll post a proper
patch and get that in for 4.14 (and possible backported as well, I'll have to
look at that).
Regards,
Hans
