SubjectV4L: Black and white quickcam enhancement
Hi Alan, everyone,

Changes to the black and white QuickCam driver in this patch:

1. Fix for missing camera parameter update if the grab size is
changed with VIDIOCSWIN.

2. Lazy updates of the camera frame data. Only update the camera
brightness/image size when we need to.

3. Addition of parameters to control the frequency of yields to the
scheduler when grabbing a frame from the quickcam. This should
avoid having 'freezes' for 1-2 seconds while a frame is grabbed.


1. Memory-mapped grabbing support.
2. Further work on the lazy update scheme.
3. SMP protection ??
4. Camera detection scheme improvements?
