    Subject[PATCH] compat_ioctl.c : VIDIOCSWIN using the wrong variable as argument


    There is a bug in the VIDIOCSWIN ioctl32. The 32->64bit wrapper passes the wrong variable to the 64bit ioctl.
    It should pass the video_window (vm) instead of the clips (p).

    The attached patch fixes this and has been tested successfully on a sparc64 with the pwc driver.
