DDP Fails to compile for ESPHome version 2025.11.0+ with VERBOSE logging

[neilflatley]

Hi,
Thanks for writing such a useful component. I have been using this for a short while without any issues until I upgraded ESPHome and rebuilt the firmware for my ESP32 device

I am getting the following attached error when compiling with the DDP component in 2025.11.5

I'd say this is related to the previously resolved issue #27 however my configuration has logging set to VERBOSE - The errors and source code point to ESP_LOGV function calls

Setting my logging level back to DEBUG allows the device firmware to compile successfully.

Having looked at the previous fixes and merges for 2025.11.0 perhaps this was a small oversight as I'd guess most configurations won't have VERBOSE logging.

Ok I just uploaded a fix for this. Let me know if it is working.
