However, even when ignoring the error, the code continues to log a DRM_NOTE. On affected hardware, this results in persistent "DisplayID checksum invalid" messages in the system log. This noise often misleads users into thinking there is a critical hardware failure or a functional regression, despite the quirk successfully handling the issue. Downgrade the log level from DRM_NOTE to DRM_DEBUG_KMS. This keeps the diagnostic information available for kernel developers while silencing the unnecessary warning for end-users.
