From 3a0a73b3c884ef43487d6c3b43af077d6da124b7 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 22 Apr 2013 12:34:13 -0700 Subject: [PATCH] staging: comedi: ni_labpc: remove unnecessary 'bustype' check Only the ISA versions of the LabPC boards support DMA and the devpriv->dma_chan is only set during the ISA board attach if DMA is available. The extra check of the board->bustype is not necessary in labpc_ai_cmd().
