From 0af125ca06afbf279c45dc5a57ec35247b35e0e2 Mon Sep 17 00:00:00 2001 From: Cong Ding Date: Fri, 18 Jan 2013 21:42:18 +0100 Subject: [PATCH] iommu/omap: Remove unnecessary null pointer check The pointer obj is dereferenced in line 146 and 149 respectively, so it is not necessary to check null again in line 149 and 175. And I have checked that all the callers of these two functions guarantee the parameter obj passed is not null.
