[PATCH v3 4/8] media: docs: make CEC documents compatible with Sphinx 3.1+

Mauro Carvalho Chehab
2020-09-25T06:31:22Z

Sphinx 3.x broke support for the cdomain.py extension, as the
c domain code was rewritten. Due to that, the c tags need to
be re-written, in order to use the new c domain notation.
