    Lad, Prabhakar authored
    Remove bogus 'numbuffers' and 'bufsize' module options. The number of buffers and
    buffer sizes are determined by VIDIOC_REQBUFS and VIDIOC_S_FMT and the amount of
    available memory (in the case of the MMAP stream I/O mode) and not by module
    options.
    
    These module params are a left-over from the original montavista code that used
    these parameters to pre-allocate the memory needed for the buffers. The code that
    allocated those buffers was never upstreamed since by the time the drivers were
    added to the kernel the TI cmem module could be used in combination with the
    USERPTR mode to reserve and pass physically contiguous memory pointers around.
    
    These days of course CMA is used instead of cmem.
    
    This patch removes these module options altogether since they no longer do what
    they originally were designed for. They should never have been part of the
    upstreamed code in the first place, so they've been pointless ever since
    2.6.32 when this driver first appeared in the mainline kernel.
