    Subject[PATCH] staging: wlan-ng: Fix problem with wrong arguments
    The function pointer scan in struct cfg80211_ops is not
    supposed to be assigned a function with a struct net_device
    pointer as an argument. Instead access the net_device struct
    in the following way:

    struct net_device *dev = request->wdev->netdev;

    sparse gives these warnings:

    drivers/staging/wlan-ng/cfg80211.c:726:17: warning:
    incorrect type in initializer (incompatible argument 2
    (different base types))
    expected int ( *scan )( ... )
    got int ( extern [toplevel] *<noident> )( ... )

    drivers/staging/wlan-ng/cfg80211.c:726:2: warning:
    initialization from incompatible pointer type [enabled by default]

    drivers/staging/wlan-ng/cfg80211.c:726:2: warning:
    (near initialization for ‘prism2_usb_cfg_ops.scan’)
    [enabled by default]
