[PATCH 15/47] [media] docs-rst: convert uAPI structs to C domain

Mauro Carvalho Chehab
2016-09-08T12:04:24Z

instead of declaring the uAPI structs using usual refs, e. g.:
.. _foo-struct:

Use the C domain way:
.. c:type:: foo_struct

This way, the kAPI documentation can use cross-references to
point to the uAPI symbols.

That solves about ~100 undefined warnings like:
WARNING: c:type reference target not found: foo_struct
