V4L/DVB (4927): Enhancements on usbvision driver
Enhance the buffer management of this driver + some corrections - linux list.h usage for buffer management - VIDIOC_ENUMSTD/VIDIOC_G_STD/VIDIOC_S_STD simplification (use of v4l2_video_std_construct) - create_sysfs : remove of warnings for video_device_create_file return code - make the driver compatible with 2.6.19 kernel version (remove slave_send and slave_recv in usbvision-i2c, change ctrlUrb_complete function prototype) - deactivated v4l2_read because this code was not the priority but working on it :) Signed-off-by: Thierry MERLE <thierry.merle@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
