Being picky:
if not check digital port for conflicts, report error.
It reads backwards. Perhaps
if (conflicting_digital_port_config(dev)) return -EINVAL;

Regarding getting more information back to the user about the error
message, we could with have a connector/crtc property, a procfs file or
an ioctl to grab a string describing the last error. A LastError
property blob might be the most convenient. Though I am not sure how
outlandish this idea is.
