From 8c79825ec861945dca5ce30db75a9673a8be8581 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 18 Jun 2015 10:54:50 -0700 Subject: [PATCH] staging: comedi: das1800: rename 'thisboard' variables For aesthetics, rename the 'thisboard' variables to 'board'. That name is more commonly used for the boardinfo pointer in comedi drivers.
