From d78757e780f1845dd5c9615169f7401c7d0d1a66 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 22 Aug 2015 08:57:02 -0300 Subject: [PATCH] [media] videobuf2-core: Add it to device-drivers DocBook Most of the stuff at videobuf2-core are ok for adding it to DocBook. Two notes here: 1) As videobuf2-core will be soon be changed, better to not spend too much efforts right now, as things will change soon; 2) struct vb2_queue has a number of private elements that are documented. As Kernel nano documentation format handles "private:" arguments, we need to put them on a separate comment block or to remove. Keeping the comments is obviously better ;) Signed-off-by: Mauro Carvalho Chehab Acked-by: Jonathan Corbet --- Documentation/DocBook/device-drivers.tmpl | 2 +- include/media/videobuf2-core.h | 10 ++++++---- 2 files changed, 7 insertions(+), 5 deletions(-) diff --git a/Documentation/DocBook/device-drivers.tmpl b/Documentation/DocBook/device-drivers.tmpl index 30ba2cf2735a..e636bbd41933 100644 --- a/Documentation/DocBook/device-drivers.tmpl +++ b/Documentation/DocBook/device-drivers.tmpl @@ -234,10 +234,10 @@ X!Isound/sound_firmware.c !Iinclude/media/v4l2-ctrls.h !Iinclude/media/v4l2-event.h !Iinclude/media/v4l2-dv-timings.h +!Iinclude/media/videobuf2-core.h diff --git a/include/media/videobuf2-core.h b/include/media/videobuf2-core.h index 22a44c2f5963..4f7f7aed9157 100644 --- a/include/media/videobuf2-core.h +++ b/include/media/videobuf2-core.h @@ -362,7 +362,9 @@ struct v4l2_fh; * start_streaming() can be called.
