From d88a440eddf288c967daed827147e1121c2ab6b5 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Mon, 16 Apr 2012 21:27:54 +0200 Subject: dac960: Remove unused variables from DAC960_CreateProcEntries() The variables 'StatusProcEntry' and 'UserCommandProcEntry' are assigned to once and then never used. This patch gets rid of the variables. While I was there I also fixed the indentation of the function to use tabs rather than spaces for the lines that did not already do so.
