- document enums with the "enum" keyword
- add a description for @dbr_size
- add missing descriptions to struct most_interface (some just need
  a ':' to be good)
- add missing descriptions to struct most_component
- use Returns: syntax for function return values
- convert most_deregister_interface() to kernel-doc notation and fix
  its parameter name
