From 720a9bece0c132a9095e997969f07d8694816bbc Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Thu, 11 Oct 2012 17:21:03 +0100 Subject: [PATCH] staging: dgrp: fix some warnings Just squashing these to get them out of the analysis queue. nd_ps_desc is an array not a pointer so comparing it with NULL is silly (be nice if gcc shouted about this). And there are some slightly pointless comparisons too.
