NAME
     ddi_dma_free_handle - free DMA handle

SYNOPSIS
     #include 
     #include 



     void ddi_dma_free_handle(ddi_dma_handle_t *handle);


PARAMETERS
     handle     A pointer to the  DMA handle previously allocated
                by a call to ddi_dma_alloc_handle(9F).


INTERFACE LEVEL

DESCRIPTION
     ddi_dma_free_handle() destroys the  DMA handle pointed to by
     handle.  Any further references to the  DMA handle will have
     undefined results. Note that  ddi_dma_unbind_handle(9F) must
     be  called   prior  to  ddi_dma_free_handle()  to  free  any
     resources the system may be caching  on the handle.

CONTEXT
     ddi_dma_free_handle() can be called from  user,  kernel,  or
     interrupt context.
