[PATCH 05/30] staging: comedi: adl_pci9118: handle master/target abort in main interrupt handler

[H Hartley Sweeten <hsweeten@xxxxxxxxxxxxxxxxxxx>]

For aesthetics, move the master/target abort detection from the DMA handler to the
main interrupt handler. This allows removing the unused 'int_amcc' parameter from
the DMA and non-DMA handlers.
