From 61c3b19f7b9eb7c7838fd35f86566230fefd6550 Mon Sep 17 00:00:00 2001 From: Corentin Labbe Date: Fri, 25 Sep 2020 20:30:11 +0200 Subject: media: staging: media: Revert "media: zoran: remove deprecated driver" This reverts commit 8dce4b265a5357731058f69645840dabc718c687. The revert is slighly modified: - Documentation/media/v4l-drivers/index.rst is ,ot restored since removed from tree - drivers/staging/media/Makefile is not restored since the zoran driver is not compilable yet.
