NAME
       usb_buffer_free - free memory allocated with usb_buffer_alloc


SYNOPSIS
       void usb_buffer_free  (struct usb_device * dev, size_t size,
                               void * addr, dma_addr_t dma);


ARGUMENTS
       dev    device the buffer was used with

       size   requested buffer size

       addr   CPU address of buffer

       dma    DMA address of buffer


DESCRIPTION
       This reclaims an I/O buffer, letting it be reused. The memory must have
       been  allocated  using  usb_buffer_alloc, and the parameters must match
       those provided in that allocation request.
