void ddi_dma_free_handle(ddi_dma_handle_t *handle);
illumos DDI specific (illumos DDI).
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.
ddi_dma_free_handle() can be called from user, kernel, or interrupt
context.
