I think you are confusing KERN_DEBUG, a logging level, with a
preprocessor #define of DEBUG.

dev_dbg is compiled away completely when DEBUG is
not defined and when CONFIG_DYNAMIC_DEBUG is not
defined.

This hex_dump facility should behave the same way.

dynamic_hex_dump should only exist when CONFIG_DYNAMIC_DEBUG
is enabled and should otherwise be invisible to driver code.
