From 726288e4aadbe53ed8f43483eb3b02c4a5385bd4 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 22 Jun 2012 16:23:04 -0700 Subject: [PATCH] staging: comedi: ni_daq_700: Remove bustype variable from the boardinfo This driver is only used for pcmcia type devices. There is no need for the 'bustype' check. Remove the variable from the boardinfo and refactor the code based on it's removal.
