By default no control events are sent to the application that caused the control value or flags change (i.e. the control(s) passed to VIDIOC_S_CTRL or VIDIOC_S_EXT_CTRLS). But if a change in one control causes a change in another control that was not part of the control(s) in VIDIOC_S_CTRL or S_EXT_CTRLS, then the application should be notified. Signed-off-by:

This makes the API for this: 1) v4l2 spec compliant 2) match that of the UVC Logitech QuickCam Sphere models For now this operates in parellel to the sysfs interface for this, but the intend is to deprecate the sysfs interface and remove it. Signed-off-by:

Doing a bunch of initialization every time /dev/video is opened, and thus for example when the udev rules probe for capabilities makes no sense, do it at driver load, resp. stream start instead. This is a preparation patch for allowing multiple opens of the /dev/video node. Signed-off-by:

Looking at the pwc buffer management code has made it clear to me it needed some serious fixing. Not only was there a ton of code duplication even internally to pwc (read and mmap wait for frame code was duplicated), the code also was outright buggy. With the worst offender being dqbuf, which just round robin returned all the mmap buffers, without paying any attention to them being queued by the app with qbuf or not. And qbuf itself was a noop. So I set out to fix this and already had some cleanups in place when I read Jonathan Corbet's lwn article on videobuf2, this inspired me to just rip out the buffer management code and replace it with videobuf2, greatly reducing the amount of code, and fixing all bugs in one go: Many thanks to Jonathan for the timely article on this !

The chances if any of these becoming NULL magically are 0% And if they do become NULL oopsing is the right thing to do (so that the user logs a bug with the kernel rather then with whatever app he was using). Returning EFAULT to userspace should only be done when userspace supplies a bad address, not on driver bugs / hw issues, so in the few cases where the check is not bogus return something else.

Reset image and image_len to NULL/0 on LAST_PACKET when we're in discard frame mode, just like we do when not discarding the current frame. The new se401 driver uses image_len for SOF/EOF detection and thus depends on this. Signed-off-by:
