From 4c354b492eeb257e65886329ba5acfb1fde81dec Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 22 May 2012 16:13:38 -0700 Subject: [PATCH] staging: comedi: remove thisboard macro in the das16m1 driver The 'thisboard' macro depends on having a local variable with a magic name. The CodingStyle document suggests not doing this to avoid confusion. Remove the macro and use the comedi_board() inline helper to get the dev->board_ptr information.
