From 7e0b3bf3abec4cd30c58e6311f913759a9e324d7 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Mon, 16 May 2011 15:28:16 +0100 Subject: [PATCH] staging: comedi: addi-data: Get rid of redundant ps_BoardInfo The ps_BoardInfo pointer in the device private data is redundant as we can just use the this_board macro to access the same data, as is done elsewhere in the code. Get rid of the pointer and change the code to use the this_board macro instead.
