Future idea: If we turned DRM_FORMAT_* into an enum instead of a
plethora of macros, we could reference the enum here. Not to mention the
code being self-documenting too.

Please prefer "&struct foo" over "struct &foo". The former makes the
struct be part of the link text.
An alternative would be to change kernel-doc to work for the latter too.
