Hi,

        I have implemented V4L2_CAP_STREAMING for the zr364xx driver (see the 
attached file). Could you review the code for me? My 
Creative PC-CAM 880 works, but I do not have any other webcam to test the 
code. Besides the streaming implementation the patch also does:

. re-implement V4L2_CAP_READWRITE using videobuf.

. copy cam->udev->product to the card field of the v4l2_capability struct. 
That gives more information to the users about the webcam.

. move the brightness setting code from before requesting a frame (in 
read_frame) to the vidioc_s_ctrl ioctl. This way the brightness code is 
executed only when the application request a change in brightness and not 
before every frame read. Is there any reason to set the brightness before 
every frame read?

. comment part of zr364xx_vidioc_try_fmt_vid_cap. Skype + libv4l do not work 
if it is there and libv4's maintainer told me it is a driver bug, so I fix it.

	This patch is needed for applications such as mplayer, Kopete+libv4l and 
Skype+libv4l can make use of the webcam that comes with zr364xx chip. The 
patch is big, if you need it splitted into small patches I can do it.

	Best regards,
