vidiocgmbuf() does this:
mutex_lock(&fh->cap.vb_lock);
retval = videobuf_mmap_setup(&fh->cap, gbuffers, gbufsize,
V4L2_MEMORY_MMAP);and videobuf_mmap_setup() then just does
mutex_lock(&q->vb_lock);
ret = __videobuf_mmap_setup(q, bcount, bsize, memory);
mutex_unlock(&q->vb_lock);which is an obvious double-take deadlock.
This patch fixes this by having vidiocgmbuf() just call the
__videobuf_mmap_setup function instead.Acked-by: Mauro Carvalho Chehab

Update 3 more new-style i2c drivers to use standard module aliasing

Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from
Conexant for their support. I am in particular thankful to Hauppauge

Based on earlier work by Jon Smirl and Jochen Friedrich.
This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.Signed-off-by: Jean Delvare

The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.Signed-off-by: Janne Grunau

Add a waitqueue to wait on when there are no buffers in the buffer queue.
DQBUF waits on this queue without holding vb_lock to allow a QBUF to happen.
Once a buffer has been queued we recheck that the queue is still streaming and
wait on the new buffer's waitqueue while holding the vb_lock. The driver
should come along in a timely manner and put the buffer into its next state
finishing the DQBUF.By implementing this waitqueue it also brings the videobuf DQBUF up to spec and
it now blocks on O_NONBLOCK even when no buffers have been queued via QBUF:"By default VIDIOC_DQBUF blocks when no buffer is in the outgoing queue."

Only attach cameras to the host interface for probing, then detach until
open. This allows platforms with several cameras on an interface,
physically supporting only one camera, to handle multiple cameras and
activate them selectively after initial probing. The first attach during
probe is needed to activate the host interface to be able to physically
communicate with cameras.Signed-off-by: Guennadi Liakhovetski

This driver provides an interface between platform-specific camera
busses and camera devices. It should be used if the camera is connected
not over a "proper" bus like PCI or USB, but over a special bus, like,
for example, the Quick Capture interface on PXA270 SoCs. Later it should
also be used for i.MX31 SoCs from Freescale. It can handle multiple
cameras and / or multiple busses, which can be used, e.g., in
stereo-vision applications.Signed-off-by: Guennadi Liakhovetski

As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.
This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.Signed-off-by: Mauro Carvalho Chehab
