From 43db48d3d2f6326c571984b7b30ab355596bb3cc Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 9 Jan 2007 11:20:59 -0300 Subject: V4L/DVB (5068): Fix authorship references Bill Dirks asked me to update his entries at kernel files, since he change his e-mail. I've also updated a few web broken links or obsolete info to the curent sites where V4L drivers and API are being discussed currently.

Officially export them. VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER Definition of ioctl and struct v4l2_register is moved from v4l2-common.h to videodev2.h. Types used in struct v4l2_register are changed to the userspace exportable versions (u32 -> __u32, etc). Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move the check into the video_ioctl2() dispatcher so it doesn't need to be duplicated in each driver's call-back function. CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2).

By allowing this header file to be dual GPL/BSD will enable sharing userspace apps between Linux and *BSD systems. It will also allow developing newer BSD licensed drivers that can be shared on Linux and *BSD. It should be noticed that most of the current V4L drivers, and v4l core itself are GPL only. This won't be changed by this patch. Signed-off-by: Michael H.
