    V4L/DVB (12239): em28xx: fix webcam scaling · 55699964

    While trying to fix an mt9v001 webcam, I noticed that HSCALE/VSCALE do
    work with em28xx + webcam. The issue is that the scaling setup depends
    on the number of visible rows/cols of the input image.
    
    With mt9v011 (Silvercrest), the resolution is 640x480. So, the scaling
    is different from a normal TV image (720x480 on NTSC). This were causing
    a wrong scaling and a previous patch disabled scaling.
    
    As each sensor have their different resolution setting, the xres/yres
    should be adjusted accordingly with the input sensor.
