Logs use either %#x or 0x%x for flags, channel mask, format, device

Preferred is %#x but 0x%x is also permitted because it is widely used.

The benefit is that it reduces ambiguity and possible confusion,
without needing to read the source code for each log.

Test: builds OK and logs are less ambiguous
