- Use new routing input defines in em28xx-cards.c - Fix S-Video settings for tvp5150-based cards (input was copied from saa7115 based cards and worked only because S-Video was selected in the default: case) - Replace VIDIOC_S_INPUT by VIDIOC_INT_S_VIDEO_ROUTING in em28xx-video.c - Remove the now obsolete VIDIOC_S_INPUT handler in saa7115.c - Add VIDIOC_INT_G/S_VIDEO_ROUTING in tvp5150.c - Add new media/tvp5150.h with the routing defines.
