From f0f2c2b5b40b5e621a47a6a274117cce77841f1e Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 12 Jan 2011 16:59:42 -0800 Subject: dca: remove unneeded NULL check The return here doesn't release the locks or re-enable IRQs. But as Andrew Morton points out, domain is never NULL. list_first_entry() essentially never returns NULL and also we already verified that the list is not empty.
