2010-10-21V4L/DVB: gspca - sonixj: Bad detection of the end of imageJean-François Moine
The 'end of image' block may be splitted between two ISOC packets. This case was not tested, so, some images could be lost and concatenated to previous one(s), raising 'frame overflow' errors.

the required one Many video drivers implement a fixed set of frame formats and thus face a task of finding the best match for a user-requested format.

2010-10-21V4L/DVB: videobuf: add queue argument to videobuf_waiton()Hans Verkuil
videobuf_waiton() must unlock and relock ext_lock if it has to wait. For that to happen it needs the videobuf_queue pointer. Don't attempt to unlock/relock q->ext_lock unless it was locked in the first place. vb->state has to be protected by a spinlock to be safe.

2010-10-21V4L/DVB: videobuf: add ext_lock argument to the queue init functionsHans Verkuil
Add an ext_lock argument to the videobuf init functions. This allows drivers to pass the vdev->lock pointer (or any other externally held lock) to videobuf. For now all drivers just pass NULL. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-10-21V4L/DVB: videobuf: prepare to make locking optional in videobufHans Verkuil
Currently videobuf uses the vb_lock mutex to lock its data structures. But this locking will (optionally) move into the v4l2 core, which means that in that case vb_lock shouldn't be used since the external lock is already held. Prepare for this by adding a pointer to such an external mutex and don't lock if that pointer is set.

2010-10-21V4L/DVB: v4l2: add core serialization lockHans Verkuil
Drivers can optionally set a pointer to a mutex in struct video_device. The core will use that to lock before calling open, read, write, unlocked_ioctl, poll, mmap or release. Updated the documentation as well and ensure that v4l2-event knows about the lock: it will unlock it before doing a blocking wait on an event and relock it afterwards. Ensure that the 'video_is_registered' check is done when the lock is held: a typical disconnect will take the lock as well before unregistering the device nodes, so to prevent race conditions the video_is_registered check should also be done with the lock held.

2010-10-21V4L/DVB: v4l2-dev: after a disconnect any ioctl call will be blockedHans Verkuil
Until now all fops except release and (unlocked_)ioctl returned an error after the device node was unregistered. Extend this as well to the ioctl fops. There is nothing useful that an application can do here and it complicates the driver code unnecessarily.

2010-10-21V4L/DVB: Deprecate stradis driverMauro Carvalho Chehab
The driver author seems to not worked on this driver since its conversion from 2.2 to 2.4. Nobody is known to have a stradis hardware for testing. As it still uses V4L1 API, BKL and probably some other old stuff, someone would need to work on it to preserve the driver. Instead of investing time and efforts to keep porting it to work with new API's, it seems better to just drop the driver. So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody cares enough to port parallel port support to gspca or to create a new driver that uses the same gspca-cpia sub-driver.

2010-10-21V4L/DVB: Deprecate cpia driver (used for parallel port webcams)Mauro Carvalho Chehab
cpia driver were re-written inside gspca driver, for USB devices. The only functionality that were not migrated is the support for parallel port, as: 1) the developer didn't find any hardware; 2) it doesn't seem important to keep support for a parallel port webcam, as this is an obsolete technology; 3) the changes at gspca for it to work with parallel port would be very large; 4) this driver still uses BKL. So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody cares enough to port parallel port support to gspca or to create a new driver that uses the same gspca-cpia sub-driver.
