From 354c00a67697fc7a56b540647ef7fe93333ed903 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 22 May 2012 17:59:07 -0700 Subject: [PATCH] staging: comedi: remove this_board macro in the rti800 driver The 'this_board' 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.
