2008-10-21V4L/DVB (9330): Get rid of inode parameter at v4l_compat_translate_ioctl()Mauro Carvalho Chehab
The inode parameter at v4l_compat_translate_ioctl() were just passed over several places just to keep compatible with fops.ioctl. However, it weren't used anywere. This patch gets hid of this unused parameter. Cc: Laurent Pinchart <laurent.pinchart@skynet.be> Cc: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Straight forward conversions to CONFIG_MODULE; many drivers include <linux/kmod.h> conditionally and then don't have any other conditional code so remove it from those.

2008-07-23V4L/DVB (8430): videodev: move some functions from v4l2-dev.h to ↵Hans Verkuil
v4l2-common.h or v4l2-ioctl.h The functions in a header should not belong to another module. The prio functions belong to v4l2-common.c, so move them to v4l2-common.h. The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header and move those functions to it.

poll_one allocated on stack struct poll_wqueues which is pretty big structure (>500 bytes on x86_64). v4l1_compat_sync invokes poll_one in a loop, so allocate struct poll_wqueues in v4l1_compat_sync (with kmalloc) and pass it to poll_one.

2007-05-09V4L/DVB (5571): V4l1-compat: Make VIDIOCSPICT return errors in a useful wayTrent Piepho
Among other things, VIDIOCSPICT sets the pixel format. Some drivers don't support all formats, e.g. cx88 doesn't support the planar formats. The compat code that translates VIDIOCSPICT into V4L2 ioctls doesn't pass on any errors, so a userspace program doesn't know if it has selected an unsupported pixel format. VIDIOCSPICT sets both the memory capture and overlay formats, and it's possible that one will be set while the other will fail, e.g. cx88 doesn't even support overlay. Also, trying to set the overlay format will fail for non-root users. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

videodev2.h The videodev.h and videodev2.h describe the public API for V4L and V4L2. It shouldn't have there any kernel-specific stuff. Those were moved to v4l2-dev.h. This patch removes some uneeded headers and include v4l2-common.h on all V4L driver. This header includes device implementation of V4L2 API provided on v4l2-dev.h as well as V4L2 internal ioctls that provides connections between master driver and its i2c devices.

2006-01-09V4L/DVB (3178): bttv VBI fixesMichael H. Schimek
- V4L2_(G|S|TRY)_FMT returned incorrect VBI start lines for PAL-M, NTSC-JP, and PAL-60. They also returned an inaccurate VBI offset. - V4L2_(G|S)_FMT and V4L2_TRY_FMT disagreed about the start of VBI capturing in PAL and SECAM second field. Note the start line fixes may break applications using VIDIOCSVBIFMT because this ioctl fails when the driver does not support exactly the requested parameters. - V4L2_TRY_FMT did not clear the reserved field in struct v4l2_vbi_format. - V4L2_(S|TRY)_FMT did not expect very large or small VBI start or count values, returning wrong (but safe) counts due to an overflow. - VIDIOCGVBIFMT confused V4L and V4L2 VBI flags. However this had no effect because the flags have the same value and bttv never sets them. - In v4l_compat_translate_ioctl() the VIDIOC(G|S)VBIFMT code did not expect V4L2 drivers supporting VBI formats besides V4L2_PIX_FMT_GREY.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
