    Subject[PATCH 33/55] input: touchscreen: atmel: Stop abusing of min_buffers_needed field
    Date
    'min_buffers_needed' is suppose to be used to indicate the number
    of buffers needed by DMA engine to start streaming.
    atmel touchscreen driver doesn't use DMA engine and just want to specify
    the minimum number of buffers to allocate when calling VIDIOC_REQBUFS.
    That 'min_reqbufs_allocation' field purpose so use it.
