From: H Hartley Sweeten Date: Thu, 13 Sep 2012 17:24:00 +0000 (-0700) Subject: staging: comedi: 8255_pci: move ni_pcidio 8255 board support X-Git-Tag: v3.7-rc1~173^2~254 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=b37c1aeed89062a82da9bf78c83db0328d08e95d;p=~emulex%2Finfiniband.git staging: comedi: 8255_pci: move ni_pcidio 8255 board support The 8255 based boards in the ni_pcidio driver are all simple memory mapped 8255 boards that don't require the dma support provided by the mite driver. Move the support for these boards from the ni_pcidio driver to the generic 8255_pci driver.
