From 22c4003364437b4a3ddd36bd19b2080f1a20d372 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 31 Aug 2016 06:44:21 -0300 Subject: [PATCH] [media] docs-rst: parse-headers.pl: use the C domain for cross-references Instead of keep using the normal reference, move to the C domain ones. Using C domains everywhere will allow cross-references between kAPI and uAPI docs.
