From 60c2820d0f6d3497975b6488e2599f8f611d8b95 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 8 Jul 2016 11:40:06 -0300 Subject: doc_rst: rename the media Sphinx suff to Documentation/media The name of the subsystem is "media", and not "linux_tv". Also, as we plan to add other stuff there in the future, let's rename also the media uAPI book to media_uapi, to make it clearer. No functional changes.
