From cf2f9224e7d0112b2a20056de7f8b23060140a1a Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 18 Jun 2015 10:54:46 -0700 Subject: [PATCH] staging: comedi: das08: rename 'thisboard' variables For aesthetics, rename the 'thisboard' variables to 'board'. That name is more commonly used for the boardinfo pointer in comedi drivers.
