    V4L/DVB (7893): xc5000: bug-fix: allow multiple devices in a single system · 48723543
    Michael Krufky 提交于
    The current code passes a context pointer in the xc5000_config struct.
    This context pointer is used in the tuner_callback function, used to
    reset the device after firmware download.
    
    The xc5000_config struct is a static structure, whose .priv member was
    being assigned before calling xc5000_attach().  If there are more than
    one of the same device type installed on a single system, the last one
    to assign xc5000_config.priv will "win", and all others will cease to
    function properly.
    
    This patch passes the context pointer in xc5000_attach() rather that
    storing it within the static struct xc5000_config.
