From: Dan Carpenter Date: Sat, 1 May 2010 02:41:09 +0000 (-0400) Subject: sctp: cleanup: remove duplicate assignment X-Git-Tag: v2.6.35-rc1~473^2~287^2~10 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b99a4d53a74ac25eb4b930eef6c745579149c571;p=platform%2Fupstream%2Fkernel-adaptation-pc.git sctp: cleanup: remove duplicate assignment This assignment isn't needed because we did it earlier already. Also another reason to delete the assignment is because it triggers a Smatch warning about checking for NULL pointers after a dereference.
