V4L/DVB (5644): Usbvision: video_ioctl2 conversion
The ioctl entry point, a big switch/case, is splitted in little functions. These functions are set as callbacks for the video_ioctl2 video4linux facility. This improves the driver memory consumption and enables the v4l1 compatibility as a side effect. Signed-off-by: Thierry MERLE <thierry.merle@free.fr> Acked-by: Dwaine P. Garden <dwainegarden@rogers.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
