ed18d0c87e V4L/DVB (12337): ivtv: Read buffer overflow
This mistakenly tests against sizeof(freqs) instead of the array size. Due to
the mask the only illegal value possible was 3.

c6711c3e6d V4L/DVB (12104): ivtv/cx18: fix regression: class controls are no longer seen
A previous change (v4l2-common: remove v4l2_ctrl_query_fill_std) broke
the handling of class controls in VIDIOC_QUERYCTRL. The MPEG class control
was broken for all drivers that use the cx2341x module and the USER class
control was broken for ivtv and cx18.

This change adds back proper class control support.

2ba588942c V4L/DVB (10544): v4l2-common: add comments warning that about the sort order
Control arrays as are used with v4l2_ctrl_next must be sorted from
low to high. Add a comment at the top of all such arrays to warn
about this.

adb65bc71c V4L/DVB (8113): ivtv/cx18: remove s/g_ctrl, now all controls are handled through s/g_ext_ctrl
videodev converts old-style controls to an extended control so the ivtv and
cx18 drivers no longer have to handle both.

37f89f9542 V4L/DVB (8104): cx18/ivtv: ioctl debugging improvements
Completely rely on the video_ioctl2 debugging facilities rather than
doing it ourselves.

Fill in some missing fields in ivtv with VIDIOC_G_FBUF.

01f1e44fe8 V4L/DVB (6088): cx2341x: some controls can't be changed while the device is busy
The driver should now pass the 'busy' state of the device to the cx2341x 
module whenever controls are set or tried. -EBUSY will be returned if 
the device is busy and the user attempts to modify certain 'dangerous' 
controls. It concerns controls that change the audio or video 
compression mode and bitrates.

The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy)
to the cx2341x, effectively keeping the old behavior for now.

1a0adaf37c V4L/DVB (5345): ivtv driver for Conexant cx23416/cx23415 MPEG encoder/decoder
It took three core maintainers, over four years of work, eight new i2c
modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced
VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding
API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac
support from Axel Thimm, (hardware) support from Hauppauge, support and
assistance from the v4l-dvb people and the many, many users of ivtv to
finally make it possible to merge this driver into the kernel.
Thank you all!
