The regex search for declarations of struct of_device_id was missing cases that had a compiler annotation such as "__maybe_unused". Improve the regex to allow for these. Use '\S' instead of specific characters to shorten the regex. That also finds some more compatibles using '.' characters. Unfortunately, these changes add ~400 more compatibles without a schema.
