NAME
     eisa_dma_disable - disable recognition of hardware requests on a DMA
     channel

SYNOPSIS
     #include <sys/eisa.h>

     void eisa_dma_disable(vint_t adap, int chan);

   Arguments
     adap Bus adapter number (zero on an Indigo2).

     chan Channel to be disabled.

DESCRIPTION
     The eisa_dma_disable routine disables recognition of hardware requests on
     the DMA channel chan. The channel is then released and made available for
     other use.

     The caller must ensure that it is acting on behalf of the channel owner,
     and that it makes sense to release the channel. The caller must ensure
     that the channel is in use for hardware-initiated DMA transfers and not
     software-initiated transfers.

   Return Values
     None

   Level
     Base or Interrupt

   Notes
     Does not sleep
